a very large and hairy member of the female sex, who looks like a donkey that just drowned in a swamp.

a swamp donkey is unlike any other of the female species. She sits by herself at bars, clubs, anywhere men might become entirely too intoxicated to remember that they pointed her out in the beginning as a dirty butt her all . She is not only ugly as hell,but huge, disgusting, and abnormally confident. Not only will she send you a beer but the bitch will steal your wallet the next day. Stay away they are the devil in true form.
I went to the bar and this swamp donkey not only bought my brother a drink but me too. after she figured he wasn't going anywhere with her ass..she tried to jack that fools wallet. bitch almost got away but she was too big to be sneaky

An impeccably ugly skinny girl missing at least one tooth, whose vagina smells like a Mexican fish market.

In baseball when the hitter hits an absolute fucking moonshot on a meatball pitch down the middle and the ball has absolutely no chance of ever landing.
Announcer: Here’s the windup now the pitch…..OH MY GOD JOHNNY HITS AN ABSOLUTE FUCKING SWAMP DONKEY TO DEAD CENTER, THAT BALL HAS ZERO CHANCE OF LANDING WHAT A SWAMP DONKEY.
