A Flake is someone who can think of any excuse not to show up to an event. They usually have little or no friends because they never show up to hang out. they are fuckin cunts on wheels who will bail on you at the last minute so they can just sit on thier fat ass an rub one out. Abondon all hope of ever being good friends with a flake. They cause nothing but anger an wasted money on gas an beers.

A Flake may call at the last minute to tell you he or she will not be attending the event or most of the time they wont call at all leaving you sitting there by yourself, looking like a real jerk off. They rarely, if ever admit to being a flake an usually stick to thier excuse that they had something more important to do.

n: flake

A person whose social and psychological outer layer slips away when under pressure. They lack integrity, resilience and robustness. For their protection they depend upon unrealistic and imaginative constructs.

(I was called out on my use of the word "flake" recently and was challenged to define it. I came up pretty much with the above definition and then went through all the other definitions that people have supplied to the UD for it. I was struck by the consistency of them - especially the self-interest and unreliability. We know who these people are ...)

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.
Jane doe promised to go out with me. She never showed up. We made plans saturday night and she came up with an excuse why she couldn't show up. Jane is a flake.

Jenny is a flake, she told me she'd go to that party with me on Friday, and she found plans with some other girl.

Someone who doesn't have the balls to tell you they're busy and can't hang out, but still makes plans to 'chillax' so you go out of your way to 'chill' with said flaker, only to have them flake out on you, and then give you some lame ass no ball excuse instead of just being straight up that they're a flakey flake
