A post shower is typical
Swamp as may be experienced while going commando on a hot day, playing basketball, sitting in a sauna, swimming, or tanning

Swamp ass, in association with lengthy road trips, is usually accompanied by the smell of stale french fries that fell into your crotch that you failed to notice.
jimmy: ok, but lets take your car, mine smells like total swamp ass.
