This is when I’m talking to her, and I imagine she’s talking back to me in her particular character. Is this objectively wrong? I am not American so I have no local cultural reference for this, but I tend to believe she is.
edit: It’s probably important to clarify, this is not with an R ending and she always uses it in a friendly manner.
Just an hour ago I tried to remind her that she already had dinner, to which her response was, “x you trippin” where x is the word. But she was wrong, she did have dinner.
