你又做了谁的蟑螂
[nĭ yòu zuò le shéi de zhāng láng]
Directly translates as 'You become another person's cockroach.' Cockroach is often perceived as a pest, unwanted and always getting crushed. However, in modern Chinese internet slang, it sometimes humorously means 'to go against someone's preferences or to be unaccepted' with a touch of self-mockery or sarcasm.
