look up any word, like blumpkin:
 
1.
The side effect of women in hot yoga class that wear light colored sweats. When the sweat from your ass heads between your legs.

Combination of Swamp puss. Also good for Swoobs: Swamp boobs, and Swass: Swamp ass.
I always wear black pants to hot yoga class in order to avoid a wicked case of swuss.

I worked out so hard today not only did I have swoobs and swass, but eww, swuss.
