Flake
alternate pronunciation - FLAKE (must be yelled)

As a noun, it is a person who is completely fake.  They constantly need attention and must be liked by everyone, even if it means stabbing someone else in the back to do it (as long as the other person doesn't find out, and if they do, everything can be solved by a *hug*).

As a verb, it means to perform a retroaction, in a manner pertaining to the noun form.  For example, ditching one friend to hang out with two friends, because two is more than one (do the math; it's true).

As an adjective, it means completely devoid of personality or character.  Also, refering to everything as "the coolest," despite the fact that there can only be one "coolest."
I enjoy a bowl of frosted flakes in the morning.
