The dickhead in the background of Armin Only: Imagine (2008) who would introduce the acts and talk absolute shit that nobody wants to hear at the most inappropriate times.
Man I wish that MC would just shut the fuck up!

Ohhh, here's that fag of an MC on stage again. I wish he would just piss off!

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..

1) A king among men
2) One who may drink any other under the table with little or no effort put forth.
That fucking Mc drank ten times as much whisky as me and he is still standing.

Synonym for 'Most Awesomely Beast'. Originating from the greek 'M' and the Latin 'C'. Often used to describe one who is better than yourself.
You jumped over that WHOLE bar!?!?
That's pretty MC, right there.

MC is short for Monster Cock. Aka, a monstrously huge penis.
"Dude, why is that girl limping so badly?"
"She probably took an MC last night"
