Turd Monger 

A Turd Monger is somebody that produces particularly strong, foul smelling bowel movements. This individual can be an extreme source of frustration to others that happen to walk into a restroom recently utilized by this culprit or happen to share occupancy in a restroom when this offender decides to unload. It can be even more frustrating if you walk into a polluted restroom unknowingly after the perpetrating Turd Monger used it, do an immediate about face and pass someone else on the way in. They immediately assume you're the pollutant and give you the look of death.

Holly shit, I was about to hit the head when I saw that Turd Monger Jimmy Brown walking out. The last time I was nailed by the fumes of his posterior emissions my eyes burned for hours. Christ, at my worst, I can't come close to what comes out of his crack. I'm surprised the smoke detectors didn't go off. No wonder the fucking ozone is disappearing!
