A person who goes into the bathroom, and tries to open your stall door over and over, even though it is obvious that someone is in there; causing you to tense up and cut off any turds in progress.
A mythical beast of Puerto Rican descent, whom resides in the small town of Alliance Ohio. Alias's include "Puedo" and not to forget "el turd burg". Famous for the the "great turd heist of 97" the Terrible Tubby Turd Burglar is still at large.
When you finally find an empty public restroom for a dump so massive that it requires complete solitude for the deposit....and then someone walks in.(especially at your office/work place)
Just as I was about to 'release the beast', some turd buglar entered the bathroom causing my sphincter to snap shut!
