Doing the M.O.

It is when you take a picture and instead of looking at the camera you stare off into the sky.

That chick is doing the M.O. Why doesn't she just look at the camera and smile.

M.O.

The office of a math department head at a high school. Often inhabited by a cult of hostile geeks who hang out there. Also used as a generally "rule-free" zone by those in the know.

Let's go in the M.O. and microwave some beef burritos and inspire explosive colon in our enemies.

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."
