a swamp donkey is like a swamp pig or a bush pig
basically its a white trailor trash scrubber who doesnt wash and has a smelly cunt
a girl u wouldnt fuck with a baseball bat
a toe up girl that hangs out in places she doesn't belong acting like she is too good for everyone and comes cheap with the giving up of the snatch. But if she was to give it up would need to be double bagged first.
There are two types of women, swamp donkeys and dirt squirrels:
A swamp donkey is there just "to take the load".
A dirt squirrel "gathers her nuts for the winter".
