Wild Ass Rash 

An acute rash of the ass which primarily occurs in the summer when humidity and temperatures are high. Its severity increases when the sufferer must walk around on hot humid days in clothing with poor breathability. It commonly affects county fair attendees primarily those in denim jeans. The feeling is comparable to shoving double sided sandpaper between ones butt cheeks and walking until the skin is raw. Probably the main reason for the creation of Gold Bond Powder.

That guy sure is walked bow legged today, he must have the wild ass rash.

My asshole looks like a clown's mouth because of this fucking wild ass rash.

I smell baby powder, who's got the wild ass rash?
