The true definition of swamp ass is only for the ultimate revenge seekers and when you really want to degrade and rob a person of their dignity for cruel things or crimes committed against you or your family. You knock them out and rape their ass and when they wake up it is your cum causing them to have the disgusting feeling of a swampy wet blown out ass.

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.
Example:

After a long day of moving furniture. "I need to go home and take a shower before I get swamp ass."
