A person who's thinking about fucking underage girls/boys and is being warned if they do, they will go to jail and be passed around like someone's bitch.
"He's going to jail for fucking that 14yr girl, and he is assbait when he goes in".

Promiscuous gay guys, or gay guys in general.
Any single gay guy at a gay bar is ass bait.
