I don't know her - A sneaky way to tell someone you think they're a total waste

A sneaky way to tell someone you think they're a total waste of space. It’s like throwing shade without even trying.

I don't know her. She’s a face I’ve never seen and never want to see again.

I don’t know her. She’s like a bad pizza, you know it’s gonna be trash.

I don’t know her. She's a ghost in my life and I'm not afraid to say it.
