If someone has their legs up in stirups gettin' ye 'ol annual & they suddenly surprise their OB-GYN with a wretched stream of explosive diarrea.
This condition is worsened when said patient sees no problem with coating their physician with a think sticky coat of leftover chinese & cake, but instead says "oops. a little bout of diarrea." It is even better when you overhear this phone conversation at work.
I was at the gyno, and did a little gyno-no-no right in his face!
When one is using the facilities and is suddenly overcome by a rancid wafting stench. This stench occurs when gasious build-up from a rotten crotch is let free without warning, so said crotches owner can take a piss... or worse.
The larger the pants (the largest referred to as tent pants) and accompaning crotch, the more overwhelming the odor. Can cause sudden, convulsive vomiting, unconciousness, and in the worst cast scenario, death.
Stay out of the loo, some crazy bitch just Unleashed the Dragon!! Holy Crap!
