Why is 我草 (wǒ cǎo) vs. 我操 (wǒ cāo) funny?
Probably a really late comment but none of the above answers truly explained the joke. 我草 literally means 头上长草 (got grass growing on one’s head), an expression used in China to say one is betrayed by one’s partner. So, to say the joke in one sentence, one fk(我操)and one got ‘grassed’(我草), that’s fked.(wo cao)
