Dick

The person that flips you off on the road. The guy that tries to steal your girlfriend. That one, really annoying, nagging person. Someone who just doesn't care! Someone with no respect for humanity. Nobody likes a dick. So don't be a dick.

Guy #1: Dude this one guy tried to run me off the road!
Guy #2: What a dick...

"Some dick took a massive dump and didn't flush!"
