Quackle - when you laugh/cackle so
hard you pass beyond the usual piggy snort sound some
people create, and instead make a full on quack. Extremely socially embarrassing for the perpetrator. Seems to be most commonly heard in backwards inbred towns in
Wales, especially from those of a belligerent and small stature, likely the result of excess mucus, smoking, and also potentially apnea caused by too frequent naps.
Person 1: Quack!
Person 2: Did you just quackle when you laughed?
Person 1: *Immediately socially isolates themselves out of shame, as is the
correct action for such impropriety*
