There are two videos by two different artists, with the same name. And both feature women who have quite extraordinary rears.
First off is the classic new jack swing song "Rumpshaker" by
Wreckx-n-Effect. Just
shake ya rump, indeed.
Then there is a more recent entry by an alumnus of
Flavor of Love, "Rumpshaker", by
Deelishis. You will forgive the fact that she can't spell when you look at her
ass-ets in motion.
