What techno dance song released in the 90s had the words 'rock it' or 'rocket' in the chorus?

The song you're thinking of may be Herbie Hancock's "Rockit". It featured a vocoded vocal and what many people claim is the first hit song to feature turntable scratching. This song, however, was released in 1983, not the 1990s. It was hugely influential in hip hop.
