Occurs on hot summer days, when the friction between one's buttocks feels as though it is creating a runny soup.
A particularly bad case of soup ass may be referred to as "soup nuts." In this case, the soup has risen up from the buttocks and is now soaking the testicle region. This may or may not be accompanied by a rash.

1. After a shower when you don't fully dry the crack area, then the rest of the day your ass is all "soupy".

2. Many wet farts lead to your ass crack being "soupy".
