2 Chainz and Kanye West want larger-than-average butts for their birthdays.

Birthdays are all about you. It's whatever YOU want to do. Rihanna wanted some "Birthday Cake," Jeremih wanted some "Birthday Sex," 50 Cent had his celebration "In Da Club." 2 Chainz and Kanye West (two dudes who DEF buy what they want on the regular) have their own wishes they'd like to make on the latest single from 2 Chainz upcoming album, Based on a T.R.U. Story. But here's the thing: when they blow out the candles, the stuff actually comes true.

Listen to 2 Chainz featuring Kanye West "Birthday Song" after the jump.

2 Chainz comes out of the gate pretty openly with what he'd like: "All I want for my birthday is a big booty girl." A simple request from the Atlanta rapper, though I don't know if they have that at Target. Kanye jumps on the track later rapping how he can't just accept regular gifts. "Last birthday, she got you a new sweater/ Put it on, give her a kiss, and tell her 'do better.'" I mean, 'Ye is one of the most fashionable dudes out there. He's got his own sneakers and clothing line. You may have to step it beyond grandma's sweater. Though I'll take that sweater if you don't want it though, Kanye.
