John: Danny was being a cheeky cunt last night.
Mark: Oh yeah I heard, didn't you end up knocking him out?
John: Yeah, gave him the left right goodnight.
Mark: Solid cunt.
To go up to your enemy in a club and bang their left cheek, right cheek. Then as they are collapsing you give them a big old headbut (nut). DO NOT UNDER ANY CIRCUMSTANCESEJACULATE (nut) ON THEM (whilst conscious).
