Jacob Upton

A self centered person that only thinks about themselves, and will talk shit about you behind your back if you ever meet him/her. If you confront a Jacob Upton about talking bad about you behind your back, he/she will lie about it and pussy out of some kind of a conflict.

Look, dad! Is that a Jacob Upton?
Yes, son. You should avoid him.

A Greg is always a very selfish person when it comes to anything. If they ever go into a social area, they will no matter what, want to feel superior to everyone else in the social setting.
