Someone who says that he/she will hang out with you, but then cancels at the last minute.

Someone that you made plans with, but then that person changes his/her mind when you've been waiting all day.

Someone that you plan on meeting, but then that person doesn't hit you back until the next day, saying "hi" like everything is alright or some s*** like that.
Sarah: Yeah, we can hang out tonight after I get off work at 7 PM. :)

Me: Alright, cool :). Just let me know where you want to meet.

*8 PM*

Me: ?

Sarah: Oh sorry, I've just been so busy today. Can we hang out next time?

Me: No. F*** you b****. Wasting my goddamn time. I hate people that flake. Say something if you can't hang out with me so I can do other s*** and not waste time seeing what's up with you.

Irish slang for being too tired to do anything.

Similar to flaking out where the person flaking would bail from a planned event, flaked is if the person never even accepts going in the first place.

Can also be used to describe you being in comfort
"I went to bed flaked, got some decent sleep."
"You coming out man?"
"Nah I'm too fuckin flaked right now, can't be arsed"
