I just call the "Yiffurs" Murries. Murr is the correct term for the bedroom suits.
I know one thing the word yiff is used to freely and with no definition or at least a real definition what's to separate furrsuit sex (fuc.king stupid) and furry hentai (amazing don't judge) there both called yiff
Humans and animals alike are sexual beings. Get over yourself.
Yiff is ******* gross. Dog **** is not hot.
Tell them to go away. :P
