A tattoo on the lower back of a female. Presence and size is directly proportional to 1) her sluttiness 2) whether or not she will swallow on the first date 3) whether she will give a male cock-rot and 4) whether or she has appeared in a gonzo-porn film will or will appear in gonzo-porn film.
Look at the size of that tramp stamp! I bet she swallows on the first date! I wouldn't go near her, though! I'd get cock-rot! With a tramp stamp like that, she must be a fluffer on a porn set!

Tara got a tramp stamp the other day, it's no suprise because she is indeed a whore who prefers to follow the herd.

One sure way of pointing out a woman you don't want to date. The tramp stamp's sole purpose is to provide a type of ID or banner for everyone to see that indeed this woman is trashy and not the kind to bring home to meet the family. It's a term used to describe the tattoo on the lower back of a woman....usually just above the butt crack.
"Man, I really liked that girl until I saw she had a tramp stamp! Everyone knows what kind of a woman puts something like that on her back."
