Fetty Wap and Kid Ink are back at it with another collaboration. Their latest banger, “Roll Sum Up,” is a smoke fest that follows last year’s “Promise.”

The duo gets high together on the new slapper, which features Fetty’s infectious hook and flow. Meanwhile, Ink rhymes about having a fistful of money and reefer.

“Let me roll some up and get high with me, baby,” Fetty sings on the hook. “You’re a star, you’re so fly to me, baby / To keep it real, your body driving me crazy / And I’m just trying to make you proud of me, baby.”

Fetty and Kid Ink previously linked up for “Promise” off the latter’s Summer in the Winter album. “Roll Sum Up” could be another precursor to Wap’s upcoming sophomore effort, following last month’s “Wake Up.”

Today also marks the release of Fetty’s first mobile racing game, “Nitro Nation Stories,” which is now available for iOS and Android.
