Somebody who is overconfident about getting into a music conservatory or some arts institution. Thinks very highly of himself, and if he plays an instrument, it is usually either a saxophone or a flute. Most importantly, this person lacks talent, and is headed for failure.

An overweight fat young man with an oversised head who topples at the slightest movement, he normaly smells of sweat where he sleeps round his boyfriends house nearly every day and complains he cant lose weight because he eats so many pasties, he enjoys the occasional cheese cake. Despite all this we still love him.
You have a hole in your trousers, YOUR SUCH A CALLUM.
Callums fist is going in your ass in a minuet.
Wheeeey pastie monster.
