cum stone

A large amount of cum in a pile that has hardened over time.

I went over Matt's house yesterday and accidently stepped on his cum stone!

CUM STONE

Where you cork up your dick hole in the middle of an orgasm. Then you stick it in a mini fridge overnight to freeze up into a cum stone. Almost acting like a kidney stone

Me and the buds made a cum stone this weekend.
