GM 

Group masturbation. Ussually includes no females, simple teenage boys jerking off in a living room. Typically watching the playboy channel. Looking is never aloud but a flash or a moon would not be considered odd.

-Hey wanna go GM at my place? I just ordered the playboy channel with my parents credit card!
-I'm so down, I'm gonna get you back for cumming in my blanket though, get your own!
