OCM

Obsessive compulsive masturbator. Basically, this describes anyone who has flogged the dolphin to a point of obsession. Some may experience blanks or blood.

OCMS

Acronym: Out of Control Midriff Syndrome

OCMS is characterized by an absence of the part of clothing responsible for covering the midriff. The result is a painful eyesore as a proverbial sea of fat bulges out of the exposed area.

OCMS is a fashion condition predominately affecting females of the overweight variety.

I was totally into this chick from my Psych class until I noticed she had a vicious case of OCMS. If that girl expects to get any action – ever – she needs to cover that shit up or lose some weight.

Ocm

It means something or someone is so awesome that you feel that word isn't enough.

"You're ocm!" "I found one hundred dollars on the stret! OCM!"
