The act of crushing a plastic and/or polystyrene cup on the head of a chum whilst they are unaware, shouting "BUTTERCUP" at the same time.

This tradition originates from the medieval era, when wealthy noblemen would smash butter-filled wooden mugs over their subordinates' heads before having them brutally executed. The reason for this practice are unknown, yet it is believed that it derives from the old legend of 'Stephen Buttermire', a cow who had been gifted with the ability to produce pure butter as opposed to milk. Peasants used to collect his seed in clay cups for the winter, and his village of Dairy-on-Sea became famous across the land because of Stephen's gift (a statue of Stephen still remains in what still stands of the medieval town).

The original Old English phrase was "Cuppeth Thy Butter", which loosely translates as buttercup in modern language. Throughout the ages, this juvenile game has remained a global phenomenon, sprouting several festivals across the world, including the 'Buttero Cuppo Del Grande' during the Spanish summer, and 'Le Fete de Coup Beurre' in Paris every seventh year.

"BUTTERCUP!"

Henry smashed the cup full-force over Jimmy's head, causing his head to fall unconciously in his boiling broccoli soup.
