Jermaine Dupri, who first signed the group to his So So Def label in 2005, paid his respects on social media as well, quoting Buddie’s line from one of the group’s well-known singles “Lean Wit It, Rock Wit It.”

“‘They call me Doctor Doc I prescribe what a nigga need’ #ripbuddy may your soul rest easy #demfranchiseboyz. #fuckcancer,” Dupri wrote.

Buddie’s DFB groupmate Parlae also took to Instagram to pay his respects.

Dem Franchize Boyz rose to fame in the 2000’s amid the influx of southern dance anthems coming out of the South.

The group—comprised of four members: Parlae (born: Maurice Gleaton), Pimpin’ (Jamal Willingham), Jizzal Man (Bernard Leverette), and Buddie (Gerald Tiller)—was responsible for Atlanta Hip-Hop classics such as “White Tee,” “Oh I Think They Like Me” and the aforementioned “Lean Wit It, Rock Wit It.”

DFB released three albums, their self-titled debut in 2004, 2006’s On Top of Our Game and 2008’s Our World, Our Way. Their final project came in 2011—a mixtape called Voltron.
