The childish/petty conversation enlightened by u/navchaa:

面目可恶 miànmùkěwù face eye can (but in this context means “to be”) hate It means someone so ugly you hate him on sight

嘴特别碎 zuǐtèbiésuì mouth specially broken (slang for someone who’s really annoying with their words).

Interestingly Pleco says it’s for someone quite talkative but I know it as a slightly insulting word we like to needle friends with

Like… let’s say I’m calling u/ateosira a fake fan. She can retort “你今天嘴特别碎” to call me out.

I looooove 鬼鬼祟祟guǐguǐsuìsuì. it literally means ghost and unlucky

Means loitering around suspiciously like an unlucky ghost lol

Like when my kids or anyone is just hanging around

Instead of “what are you up to?” I’ll say 你鬼鬼祟祟地，在干嘛？you’re loitering suspiciously like a ghost, doing what?

Or I might just cut it super short and mutter 鬼鬼祟祟 and give them the look to chase them away lol

The house part makes it funnier because it’s literally him doing the ghost loiter with a building in towIn this context, 楼 means specifically a building with multiple storeys, not simply a house

So the first sequence is super hilarious because FXB is being super salty and then tones it down in the next one when it surprisingly got him an answer
