  * **Summary:** "二五仔" (èrwǔzǎi) is a popular and highly negative Cantonese slang term for a traitor, snitch, or backstabber. Popularized by Hong Kong crime films, it describes someone who betrays their own group, gang, or company for personal gain, similar to a "rat" or "mole" in English. While it originated in Cantonese, it is now widely understood in Mandarin-speaking regions, carrying a strong connotation of disloyalty and treachery.
===== Core Meaning =====
<hanziwriter>二五仔</hanziwriter>
  * **Pinyin (with tone marks):** èr wǔ zǎi
  * **Part of Speech:** Noun
  * **HSK Level:** N/A
  * **Concise Definition:** A traitor, snitch, or informant, especially within a group like a gang or company.
  * **In a Nutshell:** "二五仔" is a powerful insult used to label someone a backstabber. Imagine a member of a close-knit group who secretly feeds information to rivals or the police—that person is a classic "二五仔". The term is deeply rooted in Cantonese culture and the gangster movie genre, where loyalty is the ultimate virtue and betrayal is the most unforgivable sin. It feels much more personal and visceral than a formal word like "traitor."
===== Character Breakdown =====
  * **二 (èr):** The number "two." Here, it doesn't just mean the number but is part of a historical or cultural reference.
  * **五 (wǔ):** The number "five." Like "two," it's part of the set phrase.
  * **仔 (zǎi):** A common Cantonese suffix, often pronounced "zai" or "zi." It's a diminutive that can mean "kid," "son," or is simply attached to nouns or adjectives to refer to a person, similar to "-er" or "-ie" in English (e.g., "shorty").
The combination "二五" (two-five) is where the meaning comes from. While there are multiple origin stories, a popular one traces back to the Qing dynasty military. It's said that spies and informants were often found in the second and fifth divisions (or "banners") of the army, making "two-five" synonymous with disloyalty. When you add the suffix "仔," it becomes a label for a person: "the two-five guy," or simply, "the traitor."
===== Cultural Context and Significance =====
The power of the term "二五仔" comes from the profound importance of loyalty (`忠義`, zhōngyì) and brotherhood (`兄弟情誼`, xiōngdì qíngyì) in Chinese culture. In many social structures, from family to business to social circles (and especially in fictional gangster societies), absolute loyalty to the group is expected. To betray one's "brothers" is the ultimate taboo.
A Western equivalent like **"snitch" or "rat"** captures the essence of betrayal, but "二五仔" often carries a heavier weight tied to this specific cultural value of group loyalty. A "snitch" in a Western schoolyard might tell on a classmate for chewing gum. A "二五仔," however, evokes images of a gangster selling out his entire crew to the police, leading to their arrest or death. The term is loaded with the cultural baggage seen in countless Hong Kong action films like *Infernal Affairs* (which was remade as *The Departed*), where the drama hinges on identifying the moles (`卧底`, wòdǐ) and traitors (`二五仔`) within the police and the triads.
===== Practical Usage in Modern China =====
"二五仔" is almost exclusively used in informal contexts and is always negative and insulting.
  * **In Arguments:** It's a serious accusation to call someone a "二五仔" to their face. It implies they have committed a deep act of betrayal.
  * **In Gossip:** People use it to describe someone who has backstabbed a friend or colleague, for example, by telling the boss about a co-worker's mistake to get ahead.
  * **Pop Culture:** It's extremely common when discussing movies, TV shows, or video games, especially in the crime or wuxia genres. "Who do you think the `二五仔` is in the gang?"
  * **Joking:** Among very close friends, it can be used hyperbolically as a joke. For example, if a friend reveals your embarrassing secret, you might jokingly call them a "二五仔." This should be done with caution, as the word is still very strong.
While it's a Cantonese term, its prevalence in media has made it a loanword in Mandarin. You'll hear it used by Mandarin speakers, especially younger people, all over China, though it remains most common in the south.

===== Nuances and Common Mistakes =====
  * **Mistake: Using it in Formal Situations.** This is the biggest mistake. Never use "二五仔" in a business meeting, an academic paper, or when speaking to elders or superiors. It is highly informal, rude slang. The proper, formal term is `叛徒 (pàntú)`.
  * **Mistake: Confusing "二五仔" with a general "Bad Guy".** A "二五仔" is not just any criminal or bad person (`坏人`, huàirén). Their defining characteristic is **betrayal from within**. A bank robber is a `坏人`. The getaway driver who rats out his accomplices to get a lighter sentence is the `二五仔`. The disloyalty is key.
  * **Mistake: Overlooking its Cantonese Origin.** While widely understood in Mandarin, remember it carries a strong flavor of Hong Kong/Cantonese pop culture. Using it can make you sound more familiar with modern slang, but it may sound slightly out of place in very traditional or northern Chinese contexts.
