or confetti eggs
are festive, hollow chicken egg shells
, filled with confetti
, meant to be thrown or broken over someone's head(usually as a surprise from behind), scattering confetti all over the person. Breaking the eggs over someone's head can be painful if done hard enough, but since the eggshells are so brittle no one normally gets hurt. This tradition is most often carried out among friends and family. Cascarones derived from Mexico
and have recently regained popularity in the southwestern United States
. They are used for many different occasions but, especially Easter
. Having one broken over your head is said to bring good luck.
