Question: what does it mean when someone is flaky?
Answer: flaky. If you are flaky, you are off-beat and you probably don't function in society quite like everyone else. If you say you'll come to a party and then forget to show up, you are flaky. People are flaky (also spelled flakey) if they are wacky and unconventional, but to say someone is flaky is not really a compliment.
