mr assumptions

A person who says he doesn't assume everything, yet does. He also probably calls the girl who broke up with him Ms. Assumptions, but he stalks the girl he used to have a thing with or date, and then assume everything she tweets and posts on instagram is about him.

Daamn my ex! Back at it again with calling me Ms. Assumptions when he's the one assuming everything is about him. He's the one assuming here - a Mr Assumptions.
