M.O.S

Multiple Orgasm Syndrome -

An ever-looming threat that hangs around the corner for all of us. Happens whenever we see someone wearing a comically sexy outfit such as jorts or socks and sandals. Results in a lot of cumming and moaning and is uncontrollable.

"Bro you shouldn't wear those jorts you don't wanna give the ladies M.O.S."

M.O.S

Stands for "Manual Orifice Sex". Describes when a man manually cuts a hole in someone and sticks his cock into the hole. This is the fastest way to get HIV.

Guy 1: "Hey dude, did you here about the one guy who killed that girl by M.O.S?"
Guy 2: "No dude I didn't, that is sick."
Guy 1: "Yah well at least he got HIV."
