Faceballing 

Also known as ballsmacking.
This is where a guy, or several guys whip out their floppy ballsacks and teabag someone, and smack them in the face with their balls.

Oh it was horrible, last night I passed out and woke up to my boyfriend and his mates smacking my face with their hairy balls!

Dude last night we totally went faceballing and did it to some idiot on the street, should have seen their face!
