Deus ex: human revolution, question about tong and Chinese language. ?

This doesn't really have to do with the game as such I was just wondering what Lauwei or luawei (however its spelled) tong says it, is it just a Chinese slang word for man or bro or something?

Thanks in advanceDeus ex: human revolution, question about tong and Chinese language. ?
