I know, I've said this before.
French used to be my favorite foreign language, but, sorry Francais, you have been replaced by the very sexy, round language of Portuguese. (Do languages have shapes to you or it that just me? For instance, German is very sharp and pointy, like a triangle; Spanish is oval.)
So here is a Portuguese 101 video (the young man is ADORABLE!)
Hello = Oi.
(In Cockney, Oi means WTF?! or Hey! or something similar.)
