kwoddledonk
A traditional sport played by countryfolk in remote taverns. It entailed smashing mugs apart on you own forehead after finishing the alcoholic beverage it contained, and would be repeated until a competitor had fallen, either due to drunkeness or a brain hemorrhage, resulting in the winner shouting "KWODDLEDONK!" & obliterating the ceramic trophy on the losers skull.
"Jeff has lost the use of his whole righthand side from playing kwoddledonk last night. The fool."
