In another case of wedding-related smashing and stomping, German nuptials often feature a Polterabend, which is a party where dishes and cookery are destroyed. And yes, it's as fun as it sounds.
Polterabends typically start with extravagant feasts and finish with the entire wedding party making as much noise as humanly possible. Dishes are smashed, and pots are clashed. Whips are often brought out and cracked to hasten the departure of any nearby evil spirits.
The origin of the tradition is unknown, but it's thought that the cacophonous sounds caused by the smashing of the cookery represent the inevitable future disturbances that the couple will face throughout their married lives. By breaking the dishes beforehand, the community is preparing the couple for the obstacles ahead and simultaneously wising them luck [source: Monger].
