Disznothor

This is a joke, which you can understand the best in Hungarian. The word "disznótor" is a feast, where a pig actually gets slaughtered. While this might sound cruel and abusive, this has been a tradition for a while, done only during the wintertime, so it can be executed safe.

We also all know Thor, but in Hungarian, you both speak the word "Thor" and "Tor" almost the same way, this leading to this joke.
