EFF

Noun. Stands for Eternal Friends Forever. An EFF is a living thing that exists between two people. When an EFF is achieved, it must be nurtured and weened until it is healthy and mature. It brings joy to those that it belongs to and, depending on the longevity of the EFF, it will grant it's master's eternal life.....that is, until it is broken.

EFF can be used to describe the actual relationship or entity...

"Omg, the EFF totally sucks today!"

...or it can be used to describe the participants of the EFF...

"Omg like you are totally my EFF k? Pengers and smeagols!"
