mark of the swamp donkey
When a girl has one of those retarded tatoos just over her ass. Any girl with one of these tatoos can usually be found at the bar on a Friday or Saturday night, with 4-10 other girls, getting drunk and puking in the parking lot after.
"Hey, check out the ass on that bitch"
"Not bad, I see she bears the mark of the swamp donkey"
