Really, I couldn't find anything that starts with I, but this is something that doesn't cease to amuse my American friends, so I'm going to write about this anyway.
It's called Locsolás, and they usually translate it to Easter Sprinkling, even though the proper term would be Easter Dousing. Really.
Basically, it's the wet t-shirt contest of our ancestors. You can't argue with it if it's tradition!
Sounds fun, right?
Listen up, guys, it gets better.
So, by the end of the day, if you are a guy, you are rich and drunk; if you are a girl, you are drenched and feel very popular. Halloween meets Valentine's Day meets Spring Break.
(In some areas of Hungary girls could return the favor on Easter Tuesday. Sometimes, if the girl refuses to get sprinkled, guys pull a trick on her. Or at least that's what my grandpa's stories are about)
Still. I think it's a fun tradition to have :)
