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.

A condition of severely sweaty butt cheeks or crotch, where the sweat and any un-wiped or leaked fluids or poo from bad hygiene combines to make a disgusting stain that not only stinks up a 10 Ft radius in a crowd but attracts a horde of flies, hundreds of which collect on the stain and feed from it. overly tight nylon pants on a big female booty exacerbate the problem by intruding into the butt crack and wicking the fetid smear to the surface. The sufferer is sometimes unaware of this and does not correct it, leading to randomly taken pictures of their fly-infested ass appearing on the internet at their expense.
Nigel: Oh man- look at that nasty whore with the big booty and red pants! Is that a brown stain in the crack of her ass or a horde of flies on a brown stain?
William: Shit man, she's got the Swamp Ass!

An unfortunate condition in which the doo doo chute and surrounding areas are wallowing in the depths of a vile, festering, putrid poo swamp. This generally occurs when the ass isn't thoroughly wiped resulting in odors eminating from the region that smell like a fresh dump.
Vandy's swamp ass reaked so badly that the smell of his freshly unwiped ass could be enjoyed nearly three rows away in the theater.

When after sitting on something for a long time while working up a sweat or working up a sweat in general your ass sweats to a rediculous amount to the point where your underwear/boxers stick to your ass. Often accompanied by a funny walk.
