You’ve got no idea what you’re talking about
This sort of phrases is used by toxic people who want to ruin your self-esteem by telling you how badly you are informed about the stuff you are talking about. These words are used to make you feel intellectually inferior to others. It is embarrassing when this phrase is articulated around other people.

You are not the kind of person I would ever like to be with
You’ve been told that you are someone who no one would ever want to be friends with. This phrase sounds like an ultimatum. It is threatening too. Your friends or partners would never say such things if they were genuine. People usually say they are not willing to be with you only when they know they are guilty as well. It is a selfish phrase said by selfish individuals who have their own flaws. They do make mistakes just like anyone else but they are not ready to admit this fact.
