look up any word, like colorful friendship:
 
1.
When the vagina leaves a stain from semen, cum, or blood on the sheets or elsewhere.
girl: My boyfriend and I had sex the other day when I was on my period and when I sat up on the bed I left some blood on the sheets.

friend: Eww! You Vagina Stamped his sheets!
