Degenerate form of the word yiff, used to denote a form of roleplaying sexual encounters. While yiff is used to denote general cybersex, Yaff is used to denote more freakish and/or pathetic attempts at textfucking, including bizarre and horrifying fetishes, poor grammar and spelling, and a total lack of attempt to formulate a coherent scene or storyline with the other participant(s).
Oh my god, I was chatting with this guy I met last night and he just wanted to yaff.

How bad?

Total disaster, it looked like a typewriter exploded while writing a horrible fetish porn novel.
