Louisiana Swamp Ass
The goo that forms in your butt crack that is caused by heavy work, usually in humid areas. Most often moist and sticky, this condition generally causes skid marks, or 7-layer underwear wrecker. The smell of this can be nauseating. If a bad enough case exists, there can be a snail trail left behind when a person stands up.
After unloading that truck in this heat, I got a wicked case of Louisiana Swamp Ass.
