Steffanie ,

Thanks a million!! I have been trying to understand it for a long time, I've asked so many people and no one could give me a reasonable answer.

BTW, your Portuguese is very good. Have you lived in a Brazil or Portugal?

 Dale,

Thanks for your reply. Since you are a native and didn't understand, I can figure out it is a slang and maybe a local one ... Anyway, it is interesting to know that even natives need some background to get it ...
