A common condition in which the ass crack and crotch becomes overly moist, sweaty, and stinky from one or all of the following:
- sweating on a hot day
- not bathing enough
- long day of work, sports, play
- incomplete wipe due to rush or laziness

The crack will often feel squishy, wet, unpleasant, and itchy. It is recommended to take a bath with soap to sanitize the condition.

An unfortunate condition in which the taint (the often hair-bespeckled, flrshy space between balls and ass) is wallowing in the depths of a vile, festering, putrid poo swamp. A generally uncomfortable, unwipable ass. The only cure is gold bond.

Swamp ass can occur during periods of intense physical activity. It is a condition where your ass becomes sweaty giving you the feeling that your ass is actually in a swamp. If not treated swamp ass can lead to a more serious condition called duck butter.

Is the condition when you sweat a lot in the ass/ball region and it releases a terrible smell. Other factors that add to the condition is not wiping properly and not showering daily.
