Grandma Jibs

A girl with an ugly face and messed up teeth, usually very obnoxious and/or overweight.

Grandma Jibs: This party is awesome!!! I'm all wasted and shit, yeah!!!

Me: Ohhh? That is neat. I'm going to call you Grandma Jibs.

Grandma Jibs: Why?!?

Me: Eh, don't worry about it.

Grandma Jibs: Cool!
