MO

MO is a word used to describe the feeling you get when a person is just chilling, typically on a couch, in a car seat, or in class and you get a sudden urge to subtley jerk into movement. Some poeple call this "getting the chills". However, the deal with MOs is that if you get 8 in one 24 hour span, you have officially had an orgasm. Bryan Matt coined this phrase.

Maura: Wow! I just got the chills.
Bryan: Hey Maura, do you know what you just had?
Maura: No.
Bryan: You just got a MO. 7 more and you are good to go.
