I personally thought it was blood, just guessing. The reason I thought this was because of in the song welcome to my hood lil wayne said young money cash money blood bitch i'm red hot, but my boyfriend said it was business but he was just guessing, too. But I now believe it is billionaires, and I will stand by that until lil wayne himself tells me otherwise. So billionaires is the one I would go with. People seem to chose it more and plus I asked cha cha and that's what she said it was. lolz
