2000s song, (fat) black guy, high pitched voice, unintelligible lyrics
So I'm looking for a song from the 2000s, it was a black guy (I think he was fat) that sings in a really high-pitched voice. The lyrics are unintelligible, it goes something like "wana mana na wana mana ..." and then like an opera female singer "Oh ! Oh oh oh, oh oh ohhhhh! Oh oh oh oh ohhhhhh ! OOOH OHHHHHH"
