"Nossa! Nossa!" means ours, ours. "Gij se vuile rossa!" sorry but that donÂ´t exist but I think that is from a song that got a little famous and even C. Ronaldo danced am I wrong? Ah and again certainly that is portuguese from Brazil haha
I know the song, cause it's been played so damn much around here my ears puke now whenever I hear it. I don't understand a word of it, though, except for "Nossa! Nossa!", so I filled in what I hear. Doesn't mean it's what he sings, cause... well... who the hell understands what he sings, eh?
