An Easter whip is a special type of whip that people in some countries use to celebrate Easter. It's a long, thin stick made out of wood, decorated with ribbons, and with a long piece of braided leather at the end.
On Easter Monday, people in some parts of Europe like Hungary, Poland or Slovakia use the whip as part of a fun tradition, called "sprinkling". Basically, young boys visit their female relatives, like grandmas or cousins, and "sprinkle" them with water using the whip. This is supposed to bring good luck and health for the coming year.
But there is a twist! The girls can fight back, and defend themselves by giving the boys painted eggs or sweets. This is kind of a game, and everyone has a lot of fun.
So, the Easter whip is a toy that boys and some girls use to play sprinkling on Easter Monday. It's like a cool-looking water gun, only in the form of a whip. And it's a way to have fun with family and friends while celebrating Easter.
