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.
