Foul Floating Filth
The nefarious process of creating a commode-filling, toilet tissue supported, shit-flotilla in an attempt to air-expose as much fecal material as possible, thus maximizing both odor and offence for subsequent, unsuspecting patrons; frequently deployed in the bathroom facilities of restaurants with poor service, gas stations with exceedingly foul rest room hygiene and other locations deserving of passive-aggressive retribution.
That restaurant had the worse service ever and the food was terrible; there'll be no courtesy flush for them; Foul Floating Filth coming right up...I've been eatin' corn and burritos , too...
