Portuguese or brazilian...not sure:(

Hello lyrics lovers..I'm looking for a song for some time, I don't know for sure if it's Portuguese or Brazilian or something close to them...the only thing I know/remember is that the chorus goes like that: fujirrrrr nah nah nah nah ohhhhhh fuuujirrr...(it could be fugir instead of fujir, sorry, I don't know the language and how to write it..) it's sang by a woman..I'm sorry if I can't give you more details..I'd appreciate any help

I've been looking for it too... here's a link to a remix of the song http://www.youtube.com/watch?v=4ET_C0lAwvs
Google Translate detects the language as Galician http://en.wikipedia.org/wiki/Galician_language; close to Portuguese.
Enjoy the song!
P.S. I love it too

I was also looking for this song for years, now found it unexpectedly, thanks to you ) They are definitely Brazilian.

Thank you so much!!!! You really made my day!!!
