Yiffer 

(Yiffer)Pronounced (Y-I-ph-r)-see (Furry) Slang for Furry. Basically Yiffers are hardcore furrys who dress up in animal costumes and have orgys. Yiffers have an unhealthy obsession with human like animals and have massive "Fur Conventions" and Furry Hentai websites. It is common for them to display animal characteristics. In many cases Yiffers think they are an animal like a fox or wolf, trapped in a human body.
*Not to be confused with beastuality.... but both equally screwed up

Pre-Yiffer 

Yiff referring to anthropomorphic pornography, often watched and made by furries.

To be a pre-yiffer it would mean to watch yiff and not be a furry.

Micheal is such a pre-yiffer, he should just be a furry.
