biffy 

(n) A person who is your best friend and you and everyone else finds him or her very attractive and or sexy and they are ignorant to this beauty. This attractiveness is not bias and is not derived from the fact that they are your best friend. They have just kind of grown out of awkwardness and stumbled into beautiful perfection.

My Biffy is the highlight of my day and the beautiful sunshine that inspires my everything.
