When a person gets in the bottom of the portajohn and the other sits on top as if to go number 2 and receives a hand job from below
She just gave me a swamp thang in the hot ass porter shitter, go in and get yours...
Titty swamp is when your boob sweat is accumulated under the said boob or boobs (or bra) and creates a layer of film that coats the skin.
Or in other words
Female duck butter
Sydney: hey Lizzie, on a scale of 1-10 how bad do you get titty swamp?
Lizzie: I'd say a 6. It get so bad that skin starts accumulating under the finger-
Sydney: what the fuck is wrong with you?
-scene-
when you take a dump and your turd is covered with stringy, mossy-looking stuff, a la after you've eaten a lot of lettuce
A took a dump and squeaked out a swamp log the other day.
A used tampon stuck on the inside of a female's undies after she takes them off and leaves it.
She's pretty nasty . She pulled off her underwear, passed out, and left her swamp log next to the couch.
Another word for one's ass or Shrek's sweet sweet ass cheeks
Bob:"FUCK MY SWAMP YOU SEXY PIECE OF NIPPLES!" John: "Look at that sweet succulent swamp."
When you are sitting for a while and sweat forms around your ass crack, making it feel like you shit yourself.
"In the middle of sixth period I had a swamp so bad my shorts stuck to my asshole."
