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.
