The barse rash is a rash you get on your barse normally during periods of humid or hot weather as a result of moisture attacking the barse. It is quite painful, getting irritated by one's underwear. Normally caused by not drying the barse thoroughly enough, and normally solved with talcum powderng the region like napalm.
Man, this barse rash is killing me. It's making me walk like John Wayne. You got any talcum powder?
