In case you failed to observe Flogging Monday this year, you may want to note this Easter Monday tradition for future reference:

In the Czech Republic and Slovakia a very odd tradition takes place on Easter Monday. The day, known as ‘flogging Monday’ or Dyngus, begins when young men visit their female friends and whip their butts with sapling branches. The whip, known as a Pomlázka, is a selection of fresh pussywillow branches with coloured ribbons attached at one end. The Pomlazka symbolises fertility. Considered as part of a traditional courting ritual the young men demand treats and vodka before they whip the girls. In some regions it is even customary to douse the girls in cold water too. Oh Eastern Europe, maybe go easy on the vodka?
