亚洲醋王
[yà zhōu cù wáng]
While literally translated to 'King of Asian Vinegar', it humorously denotes being 'extremely jealous'. The term originates from internet slang where comparing jealousy levels across cultures leads to the joke that 'Asian Vinegar is the best'. Thus, using 'King of Asian Vinegar' means someone admits they are excessively or amusingly jealous in a self-deprecating or sarcastic fashion.
