Hollow resonant rush of gas from the anus that's been trapped behind a large cork-like turd. So-called because it sounds like a wail from the hairy star wars monkey. There is usually no pause between the dropping of the turd and the guff, which follows immediately.

when you're having sex as soon as you nut in her mouth squeeze her nipples and from that warm liquid in her throat and you squeezing her nipples you should have a similar sound like chewbacca

when a female is pleasuring a male in the art of fellatio and the male ejaculates in her mouth whilst simultaneously pinching her nipple with vigor. The female then will let out a growl and gargle semen in her mouth, making a noise similar to that of the Wookie, Chewbacca from the popular film saga Star Wars.
"Ah yes my dude! I indeed received a growling chewbacca when I ejaculated into that female's mouth just 3 moons past"
