This is the asshole who comes into the public restroom and just hangs out while you're trying to drop a deuce. He may just wander around, wash his hands, or fake taking a piss. However, his main purpose is simply to stand around and annoy you - possibly for his own sexal gratification.
Dude, I was trying to drop my daily deuce at work, and this turd burglar came in. He washed his hands for like 2 minutes before finally leaving in defeat.
