A condition in which your buttocks and other nearby regions get overly moist often causing discomfort resembling the feeling of not wiping your ass. This happens typically when working in intense heat, during masturbation, refusing to wipe, and some other isolated situations. Also, this condition leads to a not so pleasant stench often leaving you extremely self-conscious if the situation cannot be remedied immediately.

Slade-"I'd been outside waiting on the bus and got swamp ass."
Bryce-"Word?"
Slade-"Word. I had to go to the bathroom and handle it quick before that fine ass new girl saw me or else she'd think I'm dirty."

The slight or severe inflamation of the inner ass cheeks due to excessive walking or running after taking a deuce. Usually a slight refuge of junk surrounds and agitates the exit region.

A condition where your butt cheeks/crack feel sweaty, usually after physical activity. The name comes from the fact that, like a swamp, your butt is moist and wet in this situation.
I get a gnarly case of swamp ass whenever I do my daily walk around the park, but drinking a lot of water and chilling out fixes it.
