A person who is the actual living worst, he does not understand social cues and invites himself to absolutely everything. The ultimate cockblock, asshole and sonofabitch. This annoying turd is not to be trifled with or taken lightly. He should be dealt with quickly and bluntly or else the parties in danger will not be able to rid themselves of his infestation.

A casual invitation / threat used by an individual that is not afraid of fucking someone up.

Go pound sand up your ass.
