No, there's no swearing in the title! On the contrary, it's all good! Just that I still have no clear clue about what this "spell" actually means! Basically, it is a Finnish Easter tradition, where on Palm Sunday kids go trick-or-treating (girls usually dressed like witches, boys.. I've seen lots of Zoro's this year), caring limbs of willow, decorated with colourful feathers and saying/wishing:
“Virvon varvon, tuoreeks terveeks, tulevar vuueks, vitsa sulle, palkka mulle.”
I can't really rely on Google Translate, as the result given is "Virvon varvon, tuoreeks terveeks, tulevar vuoeks, rod for you, pay me.", but hubby said it's a wish for health and spring revival and all that jazz! As thank you, people give candy to children, and they give back a decorated branch. Pretty!
