Today the word I’ve met is get off of me.
You can use “get off of me” when somebody is keeping touching (holding) your hand or some part of body, you do not want to be allowed to do on and on.
But, get off me is to use when you want to say “leave me alone”.
You can use without distinction of get off me or get off of me.
Get off of me
I heard from TV show Homeland.
