The slow accumulation of semen in a woman's underwear following a man's ejaculation inside of the vagina when she stands up after reapplying said underwear
1. Yeah, the sex was great but this oyster in my panties is absurd.

2. I've changed my underwear like five times but I get another oyster every step I take.

3. Bro if you wanna fuck that chick go ahead, but I'm pretty positive she has an oyster considering she has not been to the bathroom since we left the bedroom.
