Sim 

An unintelligent person; a moron; a tool. Derived from the PC game, "The Sims," where characters are known to go about their daily activities in strange, or otherwise unorganized ways that don't seem to make much sense to the players.

Man #I: ...and then he ran right into the wall!
Man #2: Hahaha! What a sim!
