grant mustain 

This type of grant is the funniest grant you'll ever meet. He's goofy, funny, smart, attractive, and all in all wonderful. He drives a cool car, and has lots of cool friends. Typically you will find grant mustain with ginger colored hair. Don't let this fool you, he may occasionally act like a blonde. He has a talent of making other humans laugh. His natural habitat is in his isolated bedroom in front of the shining green PC that he refers to as "friend". Do not mistake his computer friend as a best friend, for we all know every grant mustain has a ginger human best friend. To sum it up, a grant mustain is a pretty cool dude.

"He's been acting like a grant mustain all week!"
"I always enjoy being around a grant mustain."
"Did you hear that she went to prom with a grant mustain?"

Roy Mustang 

A character from the anime/manga series Fullmetal Alchemist.

Roy Mustang is the very picture of an attractive, sophisticated man in the prime of life. With his dark, piercing eyes and clean-shaven, baby-faced visage, the infamous colonel attracts a great deal of attention from admirers. Roy's dark hair - perhaps in keeping with his persona - is worn casually unkempt, falling over his eyes; in more formal or somber situations, however, he is known to wear it neatly slicked back. He is also DEAD SEXY... IN A MINI SKIRT!!!!

On the surface, Roy seems to be a shallow and self-absorbed man, infamous among many of his colleagues and subordinates alike for the selfish and narcissistic aura he gives off.
At the core, he is a remarkably devoted commander whose primary focus and personal duty is to his friends and subordinates. Though he hides it well behind a veil of cynicism and self-importance, Roy Mustang is a man who cares deeply about the people who trust and support him

"Have you seen roy mustang?''
"Yeah he's dead sexy, in a mini skirt!!!!"
