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.
