The unfortunate condition in which the vagina has become so inflamed by noxious toxins due to lack of hygiene. It can become swamp-like and grows more potent over time. This is as detrimental to one's social life as it is to one's underwear. The worst sufferer is a poor male who tries to copulate with the swamp pussy. This this only happens either by drunken behavior or possibly a self-destructive fetish. Known to be the cause of Swamp Cock.
Man: Dang, my tongue melted away when I tried to eat out her Swamp Pussy.
Woman: Sorry...
n. A vagina or asshole that has had sperm fermenting in it for 18 hours or more. The odor it emits is unmistakable and has a tendency to linger with a strong intensity.
Damn Earnie, I could smell your swamp pussy as you were walking up the driveway. Is this your way of showing off all your trophies from last nights orgy?
