Acronym for Marine-Only-Material. Primarily a California term. The fat homely girl(s) in the bar that no guy will talk to until a group of drunk, out of state Marines hit on her/them.
Dude let's hit up another spot, this place only has chicks with their dudes and a couple of MOMs.
There are rumors that in other states, MOMs are also hit on by normally socialized and developed members of the male species, not just Marines.
