I'm not Manumania, but let me take a guess about what he's saying.
I don't think it is a problem, if Oberto is willing to play in the NBA. He easily gets carried away, whether it is in victory or defeat. He can insult the Serbian National Team and Fans, in every language he speaks after the 2002 controversial World Championships Final. He also can insult them Serbians after Manu's last second winning shot, or shout "son of a " (in Spanish) to Stephon Marbury from the bench after the former injured him. He is emotional, but I never saw that showing those emotions affected his game. Since he is a rookie in the NBA, and he is used to talk with the refs in Europe, he will get a couple of T's this season.
