Yaffle 

English slang from the Westcountry where it means to eat noisily, greedily and rapidly without paying any attention to table manners, the quality of the food or the effect on other diners. The process is usually interspersed with grunts, belches and slobbering and would put a starving hyena to shame.

"Did you see Malcolm yaffle those cream cakes? I thought I'd puke!"

Yiffyraptor

An older male furry that preys on artists by paying for comissions with the sole intent of getting laid at conventions. May try to pass as interested in becoming a woman so he can sleep with lesbians or bi-curious underage girls. As soon as he does so, he'll stop paying.

At first I thought he was genuinely interested in my art, but then he turned out to be another yiffyraptor trying to get laid. He never even paid full price for the drawings he commissioned!
