1. Something that is so cool, hip, funky, awesome, kick-ass, or far out that it is difficult to describe. Often describes something strange or unique. Originates from the Red Hot Chili Pepper album by the same name, circa 1985.
2. Something Red Hot Chili Pepper fans describe themselves as, in a proud sense. Originally from the song "Freaky Styley" by the Chili Peppers.
A person who is very unreliable. They commit to do things but rarely follow through. They will seem sincere when they make a promise. And perhaps they honestly believe they can deliver. But don't be fooled, trusting a flake will only cause you frustration and heartache when they frequently let you down.
Andy from Hereford promised to help with the kids during the holidays, but forgot to organise his diary. Andy is flaky.
Andy from Hereford promised to spend the weekend with you, but would never commit to a date. Andy is flaky.
A person, usually male, who needs to be put in a mental institution. He thinks that he is above the rest, all the while he decides to smear his own fecal matter all over the walls. Usually has little respect for anyone but himself, and hates anyone who is better than him, and most of them are. Also usually has ugly red hair, and the person doesn't bathe often enough to be accepted into society.
Person 1: Man, if that Freaky Shane doesn't clean up his act, he's gonna end up in the mental institution.
Person 2: More like if he doesn't clean up his own shit that he smeared over the walls.
