doo-doo-tee-tee-mold

This occurs when urine and fecal matter are allowed to fester in a toilet bowl until they begin to grow mold. While this phenomenon is rarely found, it can be spotted in poorly maintained convenience store restrooms or other areas where the toilets are almost never cleaned. The sight alone is very disturbing, but the odor is extremely offensive and has been known to induce gagging and/or vomiting. It can be difficult to remove the odor from clothes that have been exposed the stench and most people just throw them away. Other locations where this can be found include vacation homes (if the occupants forget to flush before leaving), abandoned buildings (occupied by gypsies), and frat houses.
