look up any word, like cleveland steamer:
 
1.
Similar to swamp ass, except with a much more apparent effect. These effects include damp to soaking wet pants (mostly in the back and inner thigh areas), a drip or stream of sweat going down your leg or pant leg, inability to properly clench your ass cheeks due to the slippery skin shared between them.
"Dude, I'm slipping out of my seat right now."
"Why?"

"That woman's water just burst or she is leaving a sweat trail due to Third Degree Swamp Ass."

"Oh man, do you smell anything?"
"What the hell is that?"
"Sorry I have Third Degree Swamp Ass and can't hold in my gas."
