A "flake" is a malqueda. To flake or "flake out" means to not show up for something planned because you forgot or because you did not realize that you had another thing that you needed to do. It can have a connotation of someone who often does not show up for things because they are disorganized and/or forgetful. Sometimes we might say they "spaced it" but that is even more casual speech.

If you can't find words such as 'flake' in your dictionary, then you might want to look in urbandictionary.com to see if the definitions which may be given, help with your sentences.

I also wanted to add that in addition to canceling at the last minute, is commonly used for people who cancel without notice. I.e., never show up but also don't call/text, etc. You can also describe such a person as "flakey". :)

Thank you! Now I understand!

"To flake" is a slang term that means to cancel, or be unable to continue plans with someone. For example: You ask your friend Jill to go to the movies with you. Then, right before the movie is going to start, Jill sends you a message and says that she can't come. In this case, Jill is flaking because she didn't come. A person who does this a lot is called a "flake" I hope that helps!
