A stain left on a glass surface after a particularly dirty bird, usually a pigeon, has flown into it. Tends to look like an angel or, in rare cases, the rabbit from Donnie Darko.
"THUMP"
"Dammit dude, a bird just flew into my window. I hope there's no pigeon stamp, third story windows are a pain in the ass to clean."

A tattoo on the lower back of a female. Denotes the perceived correlation between having a tattoo in this location and being sexually promiscuous. The larger the tramp stamp, the more promiscuous the female, goes the common lore. Popular designs include butterflies, flowers, vines, tribal designs, wings....

The extreme sport of licking a girls tramp stamp (a.k.a. a lower back tattoo) then running away before her boyfriend kicks your ass.
