Frister

A frister serves both as a friend and a sister. This word is most commonly used between twins, for they are usually incredibly close and are both friends and sisters. A frister is the ultimate companion who you may share inside jokes with, make lunches for, and watch ridiculous movies with.

Hey frister lets go catch an uber ridiculous movie, I'll make you a nice lunch with a home made granola bar in it.
