A person who is always bailing on plans that they make. Once or twice is understandle but multiple times just shows that they dont care and it's who they are. Unreliable
Don't invite that dude bc he will always tell you he can do something but then at the last minute he will bail. He is just generally flakey.

A flake is someone who generally makes plans with you, promises to do things with or for you but can never seem to follow through. When confronted with their behavior they usually get defensive and run away.

A flake is a person of weak character. When the going gets tough, they can't handle it and give up. They tend to be the end product of parents that spoiled them rotten. Many upper middle class kids who had parents that gave them cars, toys, nice clothes and did not make them work as teenagers turn out to be useless flakes that have no concept of how to get by in the real world. Flakes tend to let their emotions get the best of them. You can tell right away if a girl is a flake because as soon as she gets dumped by her boyfriend, she is crying and sobbing to her best friends over a cell phone. Flakes are not reliable when it comes to following through on their commitments. They are used to having it easy so when they fail, they break down and blame their weakness on their friends. Flaky parents don't have the balls to discipline their kids so their kids turn out to be useless spoiled brats that couldn't change a flat tire to save their lives and waste their time on facebook, texting and shopping. Although flaky women tend to be very attractive, they are incredibly boring to be with because all they do is watch MTV and follow the latest scandals of Hollywood.
Flakes make me sick. They are sore losers who drift through life like lumps of crap because they can afford it for one reason or the other.

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."
