commonly used when someone is very pissed off at someone else, and doesn't wanna say anything and the other person automatically says are you mad at me?
Me: I'm in a bad mood. nothing makes sense right now.
Person 1: Boo hoo! the world revolves around you.
me: whatever. I have to go. take a shower or do anything else.
Person 1: are you mad at me?
Person 1: I'm sorry I didn't mean it!
