Okay, to dancealonginthelightofday, some of our traditions (before anything, let me just say that i don’t know if they’re ALL brazilian things, like, if they happen ONLY here ya know? But anyway):
Carnaval: It’s the biggest “party” in Brazil, it lasts 4 days.
Festa Junina: Something like “June Party”, i have no idea if people have this in other countries, but it’s sort of a big deal in Brazil. It’s always in June (duh), but some of it happens in July too.
We have a lot of New Year traditions. Like, when you’re spending the new year’s eve at the beach, you “jump the waves” 7 times. Underwear colors are very popular too, like “wear a yellow underwear if you want luck in this new year”, stuff like that. Jumping in the floor with your right foot when it’s midnight… etc.
When men get into colleges, some people shave their hair.
We have of course the soccer, which REALLY is a big deal for pretty much everyone in Brazil (not for me xD but anyway)
There’s the music too, like samba, pagode, etc.
There’s our folklore (is this correct?), we have A LOT of stories like “Saci Pererê”, “Boto cor-de-rosa”, etc.
Wow okay, those are the ones people suggested me :) hope it helped.
