M.O.C stands for Make Out Chick.
1. A Girl that you meet on any random night that you just see and start making out with, after randomly meeting
2. A girl that you can call up, and with no strings attached just go make out with. This is different than a F*ck buddy, strictly making out, possibly cop a feel, thats it!
Johnny says : Hey bro, what do you wanna do tonight?
Jason says : Lets go hit up the mall and pick up some M.O.C.'s!
Johnny says : TIGHT !
