A confusing/disappointing person whom you have misjudged as a reliable, that continues to vote party lines.

And is appropriately named Jeff Flake, the Arizona Senator.
Jeff Flake called for a postponement of the Kavanaugh vote, as if he cared. Then flaked out and voted with the party of deplorables anyway.

Get the Flake mug.
Someone who constantly ditches you last minute when you make plans. This type of person will continually promise you that they will be there or that this will be the last time they ditch you but they are lying.
"Hey Laurence, have you seen Amanda today?"
"No Justin, I haven't. She's such a flake!"

Someone who completely leaves people hanging constantly, this person will constantly cancel on plans or do things on their own without any care of whether a friend would like to join them.
"Yeah, Porkins is such a fucking flake. He never wants to hang out with us and constantly would rather do things on his own."

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.
Jonty promised to paint Cameron’s house. He never showed up. We made plans saturday to paint and he came up with an excuse why he couldn't show up. Jonty is a flake.

A way to describe just a little bit of snow falling, i.e., you could count the individual flakes.
