It's when you have a heated argument with another person, and he/she keeps telling you 'oh my God', by implying that they
don'
t want to hear you speak, is when you use the
Don't "Oh My God" me, which means you are right, and the person should listen whether he/she likes it or not.
Jennifer: Stop talking and listen to me. He is mine, and you should leave him alone.
Candy: Oh my God, when will you
shut up about this?
Jennifer:
Don'
t "Oh My God" me.... you know I'm right about this. He loves me, not you.
