Not here for you

When a person comes for you in a shady or disrespectful manner and you neither have the time or interest in entertaining their unwanted hostility. You are staying that you are NOT here for their foolishness and therefore don't care to further engage the situation.

Person 1: I really don't like you and I can't stand when you come around, you're TRASH.

Person 2: I really don't give two shits what the fuck you think about me, I'm NOT here for you! Please dismiss yourself from my presence.
