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.
