Any female predator lingering about bars and nightclubs (or house parties, uninvited) where they prey upon innocent, unwilling, and unfortunate young men who are too inebriated to save themselves from the impending rape at the clutches of a terrible fate. They are large, nasty, dirty, smelly and have no decent features at all. They have no self-respect or dignity, and do not have the decency to lay down and die.

Roughly three out of four carry at least one STD, but two of those do not show symptoms. At least one of every eight is actually a man with a tiny penis.

In no cases can a swamp donkey ever look good, even with the worst case of beer goggles.

Ways to remain safe include swamp out, aka wamp out.
While out on the town, a good, trustworthy wingman (or sober friend) to keep the group safe.

Swamp Donkey: also known as wamp or wamper.
I'm lucky I have wonderful friends or that Swamp Donkey may have snagged me!

A very ugly, usually fat girl who hangs around in bars and clubs waiting to sexually assault males who are too drunk to defend themselves.

A really sloppy, annoying, and usually slightly overweight sorority girl. She's most likely the black sheep of the group. This girl will be the most drunk, the most forward, and the most not attractive.
I hung out with Jess and her friends last night, but I had to leave because that swampdonkey friend of hers was all over me.

Man, check out that big group of swamp donkeys! There isnt enough beer in this whole bar to make me want that!
