A person that has just recently committed analingus and/or licking of the groin and ass crack of a person that has swamp ass. The breath of the person is so volatile its smell will remind people of the harshness of fire from a dragons mouth.
Friend 1:"Did you smell the breath of that one girl? It is the most disgusting thing I have ever experienced."
Friend 2:"No shit, I made her lick out my ass after I worked out."
Friend 1:" Oooooooh.....so you made her a swamp dragon. That is some cruel shit and yet so very awesome."
