A monstrous cock or monster cock is an unusually but pleasantly large penis. Impressive both length-wise and in girth, a man with an M.C can usually expect a round of applause whenever he disrobes. He is a God amoung men and rocks a harem of ho's, all of whom adore him. After it has been established that a man is rocking a monster cock, a first name is no longer appropriate and he should be called only "M.C".
C Dub never returned to the office that day. It was later revealed that she couldn't return after sitting on an M.C. most of the afternoon. The bitch could barey walk.

I don't care if he's broke, his M.C. is all I need.

She couldn't tear her eyes from the bulge in his pants. She had a sneaking suspicion that he was rocking an M.C..

To add MC in front of any word makes it that much more intense. It gives more meaning and more excitement.
