yiffing

Yiffing is a combination of words "sniff" and "yell" made up by MatPat's wife Steph in their livesteam for a game Dayshift at Freddy's, as she didn't know what it actually meant.

MatPat: "So, yiffing is, for those who don't know-"
Steph: "Wait, I should guess! I think that a yiff is probably a yell and a sniff at the same time."

yiffing

Usually refers to cyber sex between two or more members of the furry fandom. Originally refers to the sound that foxes make when mating. Members of the furry fandom may use the term to refer to actual sexual contact, usually in a lighthearted manner.

It is also a term used at furcons to inquire about sexual intentions between fursuiters.

The anthro fox smiled at the mass of horny furres, knowing that a good yiffing session would soon follow.
