Kiffin 

That person who is always the most annoying in a crowd. They always want to talk to you about Tennessee football, but you're like "GO AWAY!!!" That is a Kiffin. This person has no life and is pretty much wearing bright orange all the time. Yeah, those type of people will not make it very far in life.

Man, this kid at school will never leave me alone. He looks like a trustee walking over here with all that orange. He must be a Kiffin.
