You can hate me if you want, I'm not changing for nothing 

A phrase that can be said in self-defense when someone is verbally harassing you. It implies that you do not care if they hate you for what you are or what you do, and that you will not conform to their ways to satisfy them. Useful in situations involving politics, choosing sides in an argument, etc. It is a perfect saying when you are under verbal attack by hate-filled people.

Some bitch: You suck! That's because you're a Republican!
Ryan (Me): You can hate me if you want, I'm not changing for nothing.

not for nothin' 

Common big house or camp preface to a piece of advice or a warning. Its use is supposed to imply the speaker is neither bossing around nor threatening the hearer, only offering sage advice or a pithy observation. In practice, however, it is often used immediately before a verbal threat to another inmate.

Not for nothin', but your cellie is a straight-up rat. I saw him talkin' to the 5-O right after that bust up where they lugged those dudes to solitary.

Not for Nothin 

A phrase used at the beginning of a sentence, typically followed by a statement or question that could potentially upset the recipient, if not worded tactfully.
Used often in the Upper East coast, particularly New York.

Similar in definition to the term “No offense but....”

Meant to soften the blow.

“Not for Nothin but you look like you haven’t slept in weeks.”
