What is Unleash The Dragon?
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!
