I just had an idea of making a topic where we can share everything we learn.
I think that's gonna be helpful, 'cause here you can put everything (slang, grammar, expressions, vocabulary, pronunciation, idioms...etc) that we learned so far so members can learn with what the last member said.
"Flossing" = which means to pretend being better than you are or to show off.
But be careful, the word flossing has a meaning different from the slang. (Slang = Giria)
Word meaning: To floss my teeth (passar fio dental nos dentes)
Slang meaning: That man is flossing (aquele homem esta 'aparecendo/se achando o melhor')
I hope I'm helping you... who's next?
