Smigus-Dyngus Day is a Polish tradition observed on Easter Monday or Wet Easter Monday (Lany Poniedzialek) when boys douse girls with water and switch their legs with pussy willows. It is the traditional celebration at the end of the Easter Lenten season and the dietary restrictions of the season. It has at its core the pagan spring rite of pouring water and switching oneself with willows as a means of cleansing, purification, fertility and making things right with dingen—the god of nature.
It also commemorates Poland's conversion to Christianity and the baptism of Prince Mieszko in 966 A.D.
"Smigus" refers to the drenching and switching aspect of the holiday, and dyngus refers to the pranks that are played. They were once two separate customs but at some point in history, they merged into smigus-dyngus (pronounced SHMEE-gooss DIN-gooss).
Food for Smigus-Dyngus Day in the U.S.
The ubiquitous Smigus-Dyngus Casserole is an American addition to the day and a requirement to properly celebrate Polish pride in the U.S. It is made with smoked sausage and sauerkraut—traditionally the leftovers from Easter dinner. You don't have to wait for Easter leftovers, though. The casserole is a great quick meal or potluck dish any time of the year. Usually, the casserole is accompanied by beer.
Other favorite foods on this day include kielbasa, pierogies, golabki (a cabbage-wrapped burrito), krupni (a Polish honey liqueur), bigos (a Polish stew) and vodka.
