OMC

Stands for "old man cock"

Sometimes used to disguise actual meaning when the company around you would take offense to you saying "old man cock."

As in, you can't interact with a webcam (ie. on Chatroulette) without some old man cock popping up on the screen once in a while.

I like to start my day off with a bit of OMC.

You know who has the best OMC? Your dad.
