Smiffed

The act of smacking someone hard across the face. Like Will did to Chris.

Man, that guy just walked up to him and smiffed him like a bad child. Yo keep it up and I'm gonna smiff yo ass. That chick was smiffing the hell out her old man.

Smiff; smiffing; smiffed.

If you keep acting up, I'm gonna smiff yo ass; Damn, that dude is smiffing the hell out his girl; Man, did you see lady smiff her old man?
