It was released on February 24, 1999 as the second single from his 1998 album 400 Degreez . The song was Juvenile's biggest hit single until the release of "Slow Motion" in 2004, peaking at number 19 on the Billboard Hot 100 . </P> <P> Also performing verses on "Back That Thang Up" are the song's producer, Mannie Fresh, and Juvenile's fellow Hot Boy, Lil Wayne . Wayne's verse ("After you back it up and stop / then drop, drop, drop, drop it like it's hot .") popularized an expression for a certain type of sexually suggestive dance; the expression was later re-popularized by Snoop Dogg with his number - one hit "Drop It Like It's Hot". Lil Wayne's verse was repeated on his 2008 single, "Lollipop". Drake samples the song for his song "Practice" from his 2011 album Take Care . </P>

Who sings when you back that thing up
