The song's title is a reference to the famous children's rhyme dance game Little Sally Walker.
Lil Sally Walker, uh, shake it proper, uh
Bend it over, make it wobble, uh, got a lotta buns
Pick it up and drop it, uh, for the proper funds
Anything to make the profit come, get them dollars, hon'
The song interpolates the popular nursery rhyme and follows the same flow, but Iggy spins the kiddie tune into a hater-bating, twerking anthem.
