The most amazing boy you'll ever meet!! You'll fall in love intantly! At first he'll seem shy, and nerdy, but once you get to know him, he's super insane, and will make you smile 24/7. Callum is an amazing friend, and if he becomes more than that, never let him go, no matter the distance between you. He'll make an effort to see you, and talk to you as often as possible. He is truthful, beautiful, hilarious, and amazing.

Callum's are very generous, sexy, loving, caring, sweet, sensitive, HOT, humorous, good to cuddle, sexy body and very good in bed. They are there to help you in any situation and always there for a shoulder to cry on.

A truly madcore human being who prides himself on nothing more than waking up every morning and thinking, "Fuck, I'm, such a sick cunt".
Typically, this individual's mad skills are admired by his peers, who aspire to live in his shadow.

Guy#2: Dude! Don't even say his name! We just call him 'God' around here.

Guy#1: Please dont tell him I said that.
