A fancy term, usually used by formal businessmen and rich gentlemen, when they see "dat ass".
Mostly used during
dinners party and high-class social
gigs.
The two "
n's" represent the ass.
James: Oh damn! Look a that girl's ass.
I'd hit it from the back, right lads?
Bob: I'd have a go on her.
Horatio: Oh quite! That is the professional
bunnage we all know and love.
