An overtly extreme case of sweating that results in or produces a vertical line of sweat over the crack of one's ass, typically caused by vigorous exertion. Could also be known as "water on the rear"
At the gym I saw a girl come out of the cardio kick boxing class and she had a severe case of vertical swamp ass. Gross.

when your ass is already sweaty from physical activity and you have a really moist fart, causing the sweat to turn a sickkish greenish brown like a swamp.

When you feel awkward about a situation and ask some other person's opinion about it and things suddenly become more strange than before causing you to ask another swamp-question, which will eventually pull you deeper and deeper in the swamp.
*You kissed a girl's head on a party and later on ask her if she was pissed at you*
Boy: "Hey, remember when I, like, kissed your head?"
Girl: "Yeah sure"
Boy: "So, uh, are you pissed at me for doing it, 'cause you've not been talking to me for days now"
Girl: "Why should I? Didn't it use to be a friendship-kiss?"
*feels strange now*
Boy: "Yeah of course it was, was it to you? (Shit, I'm quite good at asking Swamp-Questions...)"
etc.

Keegan: "Stay away from my children, please."

In the summer when its hot and your ass is wet from sweating you place it on someones face while they are sleeping or passed out.
Its 90 degrees out your sweating and your sleeping friend whom pissed you off earlier is about to wake up to the rank smell of ass after you give him a Swamp Donkey
