What is Chewbacca's Growl?
1.
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.
"Mother, would you mind closing the bathroom door, the whole street heard that chewbacca's growl"
