gynocaching

A derivative of geocaching, in which a female discretely leaves behind a personal item (earrings, lip gloss, thong, etc.) at a man's home after engaging in sexual intercourse, in hopes that the next female he invites to his home will discover it and thus, cock-block and/or create drama for the man.

From the Greek term GYNO, meaning "of the vagina." Therefore, if a man partakes in this activity, he's a pussy.
