When talking with black people this mean "They got WASTED." Although I'm white and I've never been to a black party where someone acted a fool, I don't think it involves any violence. Harmless pranks. Drunk and hitting on your brother's girlfriend. Forgot how to do the HUSTLE!!! Wished that MF would just SHUT UP!!
Ah, man. That nigga acted a fool at the party on Sunday (yes they party on Sunday and Monday and )
If you come to my party you betta not act a fool.
