Similar to swamp donk; but a legitimate term on its own and one that is easier to say.
Refers to a female or male (though the term is typically applied to chicks) who at one time might have been 'clean' (i.e., a dog) but that has now become dirty, annoying and untouchable (because it plays in swamps).
One who is so crazy wierd that they seem to creep instead of walking, or laugh instead of talking, who, if aproached you and asked where a member of your family was, would make you want to run away and take a shower. The creepiest of land mammals, the dirtiest of men.
Dave: Man, that Beatty kid is a real swamp dog, creepin' round an' such.
Mike: Shit, I'm goin' home.
After feeding a Tijuana hooker copious amounts of tacos topped with hot chilli, you cable tie her to a bed and wait for her bowel to move. Once she starts to shit you shove your cock in her burning asshole then wipe her shit in her eyes, thus making her howl like a Mexican Swamp Dog.
Continue the process wiping as much as you can on her to make her look like a Mexican Swamp Dog as well as sound like one. Finish by busting a nut on her lips to make it look like she has rabies.
I was in Tijuana for business, so I picked up a hooker named Margarita and she let me give her the Mexican Swamp Dog
A sexual deed that is sure to get the Dr.Pepper flowing in Waco.
When you are skinny dipping in Lake Brazos, pretend like you are dead and do the dead man's float. As you float by someone in the water, quickly come to life and fist them in the a-hole or v-hole respectively.
Don't forget to wear the proper protection- a welding glove covered in sand paper.
