• Summary: “神经病” (shénjīngbìng) is a versatile and common Chinese term that every learner will encounter. While its literal meaning is “neuropathy” or “mental illness,” it's overwhelmingly used as a colloquial slang term equivalent to “crazy,” “insane,” or “nuts.” Understanding when to use “shénjīngbìng” as a playful jab between friends versus a serious insult is crucial for navigating modern Chinese conversation. This page breaks down its dual meaning, cultural context, and practical usage.

• Pinyin (with tone marks): shén jīng bìng
• Part of Speech: Noun (can be used colloquially as an adjective)
• HSK Level: HSK 6 (as a formal medical term)
• Concise Definition: A neurological or psychiatric disorder; (slang) a crazy or irrational person.
• In a Nutshell: Imagine the English word “psycho.” It has a clinical origin but is now almost exclusively used informally to describe someone or something wild, irrational, or outrageous. “神经病” functions in the exact same way. It's a formal medical term that has been co-opted into daily slang. You'll hear it shouted in traffic, teased between friends, and used to describe an unbelievable situation far more often than you'll hear it in a doctor's office.

• 神 (shén): In this context, this character means “nerve” or “mind.” It can also mean god, spirit, or deity in other words. Think of it as relating to the “spirit” or the nervous system.
• 经 (jīng): This character means “channel,” “pathway,” or “to pass through.” It's the same character used in words like `已经 (yǐjīng - already)` and `经济 (jīngjì - economy)`.
• 病 (bìng): This character simply means “illness,” “sickness,” or “disease.” You see it in `生病 (shēngbìng - to get sick)` and `病人 (bìngrén - patient)`.

When combined, 神 (nerve/mind) + 经 (pathway) + 病 (illness) literally means a “nerve pathway illness”—a perfect description for a neurological or psychiatric disorder.

The dual nature of “神经病” reflects a complex aspect of modern Chinese culture regarding mental health. On one hand, there is still a significant social stigma attached to clinical mental illness. A formal diagnosis of `精神病 (jīngshénbìng)` or a serious accusation of `神经病` can be deeply shaming. However, its widespread use as a casual insult or exclamation has somewhat diluted its clinical meaning for the younger generation. In this way, it's very similar to how words like “crazy,” “insane,” or “psycho” are used in American culture. We use them to describe a funny friend, a bad driver, or a wild party, effectively divorcing the word from its serious clinical context. The key difference for a learner is that the line between a lighthearted joke and a serious insult with “神经病” can be thinner and more dependent on the relationship between the speakers. While you might jokingly call a new acquaintance “crazy” in the West, calling a new Chinese acquaintance a “神经病” would almost certainly be taken as a grave insult. Its use is reserved for people you know very well or for situations of genuine anger and frustration.

The connotation of “神经病” depends almost entirely on tone and context.

• As a Medical Term: In a hospital or clinical setting, a doctor might use `神经病` to refer to a neurological disorder (like Parkinson's) or `精神病 (jīngshénbìng)` for psychiatric disorders. This is the rarest usage a learner will encounter.
• As a Serious Insult: In an argument, shouting “你神经病!” is a powerful and offensive way to call someone irrational, deranged, and not worth listening to. It's a very common insult in heated moments.
• As an Exclamation of Frustration: This is one of the most common uses. If someone cuts you off in traffic or your computer crashes for the tenth time, you might exclaim “神经病啊!” (shénjīngbìng a!). It's directed at the situation or person causing frustration, meaning “This is insane!” or “Are you crazy?!”
• As a Playful Jab: Between very close friends, “你真是个神经病” (nǐ zhēn shì ge shénjīngbìng) can be a term of endearment, meaning “You're so nuts/silly.” This usage is all about a light, laughing tone of voice.

• Example 1:
  • 你神经病啊！开车不看路吗？
  • Pinyin: Nǐ shénjīngbìng a! Kāichē bú kàn lù ma?
  • English: Are you crazy?! Do you not look at the road when you drive?
  • Analysis: This is a classic example of using the term in anger and frustration. The particle `啊 (a)` adds to the exasperated tone.
• Example 2:
  • A: 我们明天去爬珠穆朗玛峰吧！ B: 你有神经病吧？
  • Pinyin: A: Wǒmen míngtiān qù pá Zhūmùlǎngmǎ Fēng ba! B: Nǐ yǒu shénjīngbìng ba?
  • English: A: Let's go climb Mount Everest tomorrow! B: Are you nuts?
  • Analysis: Here, it's used to express disbelief at a completely ridiculous or impossible suggestion. `有病 (yǒu bìng)` is a common shortened form.
• Example 3:
  • 我最好的朋友总是有一些神经病一样的想法，但是特别好玩。
  • Pinyin: Wǒ zuì hǎo de péngyou zǒngshì yǒu yìxiē shénjīngbìng yíyàng de xiǎngfǎ, dànshì tèbié hǎowán.
  • English: My best friend always has some crazy ideas, but they're really fun.
  • Analysis: This demonstrates the playful, adjectival use among friends. The context (“best friend,” “fun”) makes it clear that this is not an insult.
• Example 4:
  • 医生说，这种神经病需要长期的物理治疗。
  • Pinyin: Yīshēng shuō, zhè zhǒng shénjīngbìng xūyào chángqī de wùlǐ zhìliáo.
  • English: The doctor said this type of neurological disease requires long-term physical therapy.
  • Analysis: A rare but important example of the literal, medical meaning of the term. The context of `医生 (doctor)` and `治疗 (treatment)` makes the meaning clear.
• Example 5:
  • 别理他，他就是个神经病，跟他吵架没意思。
  • Pinyin: Bié lǐ tā, tā jiùshì ge shénjīngbìng, gēn tā chǎojià méi yìsi.
  • English: Ignore him, he's just a psycho. It's pointless to argue with him.
  • Analysis: Used here as a serious dismissal of someone's character, labeling them as irrational and not worth engaging with.
• Example 6:
  • 这部电影的剧情太神经病了，我完全看不懂。
  • Pinyin: Zhè bù diànyǐng de jùqíng tài shénjīngbìng le, wǒ wánquán kàn bù dǒng.
  • English: The plot of this movie is too insane, I can't understand it at all.
  • Analysis: This shows how it can be used to describe a thing or situation, not just a person. It means “illogical,” “absurd,” or “nonsensical.”
• Example 7:
  • 你是不是有神经病？大半夜不睡觉，在唱歌！
  • Pinyin: Nǐ shì bu shì yǒu shénjīngbìng? Dàbànyè bú shuìjiào, zài chànggē!
  • English: What is wrong with you? Singing in the middle of the night instead of sleeping!
  • Analysis: A common rhetorical question format (`是不是…`) used to scold someone for their unreasonable behavior.
• Example 8:
  • 我今天工作压力太大了，感觉自己快成神经病了。
  • Pinyin: Wǒ jīntiān gōngzuò yālì tài dà le, gǎnjué zìjǐ kuài chéng shénjīngbìng le.
  • English: I was so stressed at work today, I feel like I'm going crazy.
  • Analysis: A great example of self-deprecation. The speaker is exaggerating their own stress level in a relatable way.
• Example 9:
  • 他这个人有点儿神经病，你最好离他远一点。
  • Pinyin: Tā zhège rén yǒudiǎnr shénjīngbìng, nǐ zuìhǎo lí tā yuǎn yìdiǎn.
  • English: That guy is a bit of a lunatic, you'd better stay away from him.
  • Analysis: The phrase `有点儿 (yǒudiǎnr - a little bit)` softens it slightly, but this is still a serious warning about someone's unstable or unpredictable nature.
• Example 10:
  • A: 我要把我所有的钱都捐了！ B: 你可别犯神经病！
  • Pinyin: A: Wǒ yào bǎ wǒ suǒyǒu de qián dōu juān le! B: Nǐ kě bié fàn shénjīngbìng!
  • English: A: I'm going to donate all my money! B: Don't you go and do something crazy!
  • Analysis: `犯神经病 (fàn shénjīngbìng)` is a common collocation meaning “to have a fit of insanity” or “to do something nuts.” It's a strong warning against an irrational action.

• The Biggest Mistake: Misjudging the Relationship. This is the number one pitfall. Using “神经病” playfully with a stranger, teacher, or boss is a huge mistake. It will be interpreted as a direct and severe insult. Reserve the playful usage for people you know are your very close friends.
• False Friends: “Neurotic” vs. “神经病”. While related, “神经病” is not a good translation for the specific psychological term “neurotic.” The more accurate Chinese term for neurosis is `神经官能症 (shénjīng guānnéng zhèng)`. Using `神经病` in a conversation where you mean “neurotic” (e.g., “He's a bit neurotic about cleanliness”) would sound like you're calling him “insane about cleanliness,” which is much stronger and more insulting.
• Incorrect Usage Example:
  • (Student to teacher): `老师，您今天的想法有点神经病。` (Lǎoshī, nín jīntiān de xiǎngfǎ yǒudiǎn shénjīngbìng.)
  • Why it's wrong: This is extremely disrespectful. It translates as, “Teacher, your idea today is a bit insane.” Even with `有点 (yǒudiǎn)`, it implies the teacher is irrational. A better, more respectful way to express disagreement would be `老师，我不太明白您的想法 (Lǎoshī, wǒ bú tài míngbai nín de xiǎngfǎ - Teacher, I don't quite understand your idea)`.

• 有病 (yǒu bìng) - Literally “to have sickness.” A very common, abbreviated, and aggressive slang version of “你是不是神经病?”. Means “Are you sick (in the head)?” or “What's wrong with you?”.
• 疯子 (fēngzi) - “Madman,” “lunatic.” Generally more intense and less playfully used than “神经病”. It almost always carries a strong negative connotation.
• 精神病 (jīngshénbìng) - “Mental illness,” “psychiatric disorder,” “psychosis.” This is the formal, clinical term. If you want to talk about mental health seriously, this is the more appropriate word, though it also carries a heavy stigma.
• 奇葩 (qípā) - A modern slang term for an “oddball,” “weirdo,” or a bizarre thing. It's much lighter than “神经病” and often used with a sense of amusement or amazement at someone's eccentricity.
• 变态 (biàntài) - “Pervert,” “abnormal,” “deviant.” This is not about being “crazy” in a general sense, but about being strange in a creepy or morally deviant way, often with sexual undertones.
• 傻 (shǎ) / 傻瓜 (shǎguā) - “Stupid,” “foolish,” “idiot.” This refers to a lack of intelligence, not a lack of sanity. Can be used playfully (`你这个小傻瓜 - You silly fool`) or as a serious insult.
