Yiff is part of a range of onomatopoeic words that form a pseudo-language used by the furry role-playing community: yiff, yip, yerf, yaff, yarf, growf, and growlf (in order from most positive connotations to most negative connotations). Yiff meant yes or an exuberant hello!. Later, yiff was assigned a meaning of a sexual proposition, a meaning that had previously been assigned to yipp (a coarse form of yip).

    The Guardian, 4 February 2016:

    Stereotyped as less innocent than they look by mainstream media, furries tend to get a bad rap. A 2001 Vanity Fair article brought up both bestiality and plushophilia (sexual attraction to stuffed animals), and defined furry fandom as “sex, religion and a whole new way of life”. The show Entourage presented a pink bunny fursuit as a sexual prop, and in CSI-episode Fur and Loathing in Las Vegas, furries are portrayed as fetishists mainly in it for the “yiff” – furry porn or sex.
