"Listen, you Malibu middle class Barbie piece of shit, I'm tryin' to work here. Work? You ever work? Yeah, I'll bet you have. Scoopin' ice cream to your shitheel friends on summer break."
A lazy person. Someone who wouldn't expend the energy to wipe the shit they stepped in off their shoes. Someone who would shit in bed and kick it out with their feet.
Bill never has any money. He doesn't work, and sits around all day watching TV and eating potato chips, he's a real shitheel.
1. An obnoxious stupid person who is totally unaware that others are disgusted by them.
2. Someone who is unaware they have excrement on their shoes or feet.
My neighbor's kid is a worthless shitheel who can't even drive a lawnmower in a straight line.
