Question: are you freaking kidding me meaning?
Answer: In "you're such a freak", "freak" is used to say that someone is weird. In "you're freaking kidding me", "freaking" is used as a way to express annoyance. It's like a less vulgar way to say "fricking" or "f*cking". In "you're freaking out", "freaking out" means that someone's is panicking.
