look up any word, like blumpkin:
Noun; A woman's tatoo.
A women's body art.
Tramp stamp

"I dig her tramp stamp on her lower back."

It suggests that women with tatoos are sometimes a little more experimental with their bodies so maybe they are more experimental with other things too.

Another way to describe a hickey.
Damn, girl....that boy sucked your neck and gave you a "tramp stamp".
