Known as the kissing ritual, Omed-omedan is celebrated on the day after Nyepi (the silent day) to welcome the Çaka new year. The single Sesetan boys are probably the happiest on this day, for they get to kiss the single ladies of their village without any consequences. During OmedOmedan bachelors and bachelorettes aged 17-30 of Sesetan gather on the area’s main street. Divided into two groups (men and women), they will take position and face each other; at a given signal, both sides will approach to the centre of the street, and male participants will pull and kiss (sometimes forcefully) the female participants while the rest of the villagers in the audience pour buckets of water over them.
