`赖皮` is a powerful social accusation because it directly attacks a person's character and their respect for social harmony and fairness. In a culture where maintaining
面子 (miànzi), or social face, is crucial, to `赖皮` is to publicly demonstrate that you don't care about your own reputation or the feelings of others. It's a violation of the unspoken social contract that governs interactions, from children's games to business deals.
