Easter Monday Sprinkling is an old Hungarian custom. Young men would sprinkle cologne or water on the ladies of their fancy, often extended to all the women in the house or the village. Mother told of a Canadian boyfriend who upon hearing of the tradition showed up at their house and woke the family at the crack of dawn on Easter Monday with a bottle of perfume to be the first to sprinkle her. A sweet gesture not much appreciated by her tired parents.
Apparently some communities take it quite a bit further, drenching the girls with buckets of water.
