Similar to male teabagging, a female squats over someone’s face and lowers her vagina onto the person. Gash Mash is used as a practical joke or prank when performed on someone who is passed out or asleep. It can also be a sexual act as well. Another name for a vagina is gash.
At the sorority house last night, silly Sally drank 3 bottles of Boone's Farm wine passed out on the floor again, but this time the whole pledge class gave her a Gash Mash! Like, tots embarrassing!
