You lip

Basically, it means shut up. You just say 'you lip' in place of shut up.

Usually, the person saying it closes their hand with their thumb at the bottom and their four fingers at the top as they say it.

Weird Boy: Hi, how are you today? I'm alright, are you alright? Yes...?

Normal person: You lip.
