Yiff in Hell” is a phrase used by those that oppose the furry fandom, directly aimed towards furries as a message to take the activities commonly associated with yiffing elsewhere

On 4chan, “Yiff in Hell” is typically found in Furry threads, used as a protest towards furries in an attempt to lower the amount of furry content posted on the site. While it has been seen spammed throughout threads in great numbers, certain self-identified furries have offered rebuttals stating that the argument doesn’t make sense

This is the proper meaning, rather then the "Other ones" trying to insult the Furry Fandom
