M.O.M. 

move-on man. The guy girls use to move-on after a break-up. Kind of like a rebound except the girl doesn't expect the relationship to go anywhere. M.O.M.'s are dumped when the girl either finds some confidence or another man.

Girl: No, it's nothing serious... he's just my M.O.M. I'm just not over John yet.

M.O.M. 

Malignant. Oppressive. Monster.

The woman who believes that birthing you gives her everlasting control over your life. It was twenty years ago... get over it.

"Dude, my M.O.M. is such a bitch!"

M.O.M. 

An acronym for “Motorcycles Over Muscle-Cars.” Used mostly by vehicle lovers to clarify that they prefer motorcycles over muscle-cars.

“Dude, did you see that sick ‘69 Challenger?”
“Yeah, it was cool, but I’m more of a M.O.M. guy.”

M.O.M. (is my other man in girl lingo.)
In this day and age, some women need a M.O.M. (my other man) for freshness.

Wow, yeah I know, her boyfriend is not aware of her M.O.M. But she likes it that way.
