The origin of this problem is the ass crack. Once sweaty it begins to get itchy, like you did not wipe well enough. After it gets unbearable you begin to scratch like crazy, and shortly thereafter your whole ass feels like one big cactus has spanked you for hours.
John and Bryan were walking home at a fast pace; Due to the intense friction, John's ass crack began to sweat and itch. Result, Swamp ass.

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.
