王八算什么老娘是乌龟
[wáng bā suàn shén me lăo niáng shì wū guī]
Expresses defiance by turning an insult around into a humorous challenge or comeback. 'A turtle (wang ba, slang term for cuckold/cheater) isn’t anything! Your grandma here is the turtle (a self-referential twist).' This name turns traditional insults on their head in a light-hearted fashion.
