SEM - Selective Edited Memory 

When you are involved with a chick that recalls certain things of the conversation but edits what was said to throw something in your face. Worse then paraphrasing. It was more commonly referred to as "psycho bitch" in the 90's until scientific advances were made in the origins of such behavior.

Mike: She told me that I told her to stop loving me. Definitely has SEM - Selective Edited Memory.

Tom: Isn't that called psycho bitch?

Sem 

This nigga is loved by everyone. Either you love him and if you don’t you probably don’t know him. He is one of the kindest people you know, he puts others before himself regardless. He is really strong considering his size. People under estimate him all the time. He got hella chicks on the low. He probably doesn’t need you but believe me when I say, YOU NEED HIM.

Sem is a real friend
