Here are some more brazilian slangs:

"falsiane" it's someone who you cannot trust, who's always fake with you.

"cara", "vei", "lek" similar to dude 

"neguinho" is always someone whose name isn't said. It's similar to "he" and "her" (works for both) and very informal I would say. 

"Tipo" it's kind of an informal interjection. In Rio people can't complete a phrase without "tipo" in it. It gives the idea of "I was at the beach AND THEN (e aí tipo) he showed up in front of me"

"tá ligado" Gives the idea of ...you know?" at the end of a phrase. "He said he doesn't want to keep up with this, you know?"

"seje menas" it's a wrong way to say "seja menos" and it means something like "Stop. You're too over, be less." 

"Partiu?" and "bora" means "let's go"

"Deixa comigo" ou "xá comigo" means "I got your back"

Deu ruim" means "something went wrong"

"Pela saco" is someone who's is always doing something for someone, keep around them, who agrees with everything that person say and doesn't have personal opinion.

"Patricinha" is how we call the girls who are too girly. Regina George, from mean Girls, is a "patricinha" and the movie "Clueless" in Brazil is called "As Patricinhas de Beverly Hills"

"kiridinha" is how we say a rude "darling" like "darling, please. You're a shame."

And that's it for today. I could name a few more, but I guess it's enough. Isn't it? Hahaha
