"Smack My Bitch Up" is a song by English electronic dance music band the Prodigy. It was released in November 1997 as the third and final single from their third album, The Fat of the Land (1997). In 2013, Mixmag readers voted it the third greatest dance track of all time.[4]

The song caused considerable controversy because of its suggestive title and explicit music video, which depicted scenes of drunken and drug-fuelled sexual assault and violence. The refrain, which consists only of the line "Change my pitch up/Smack my bitch up", was sampled from the song "Give the Drummer Some" by the Ultramagnetic MCs. The song also contains a brief medley of Shahin Badar vocalising alap. In 2010, it was voted as the most controversial song of all time in a survey conducted by PRS for Music.[5]

Director Jonas Åkerlund's music video for "Smack My Bitch Up" was rarely seen on television due to its controversial subject matter. The video, filmed entirely in first-person perspective, depicts a drug-and-alcohol-fueled night out through the eyes of a mostly-unseen character, and utilises different camera movements,[11] through a 35 mm film camera attached to director of photography Henrik Halvarson's head,[12] corresponding with the protagonist's altered state of mind.[11] This character first showers and dresses, then drinks vodka and sniffs cocaine before going out. At a bar, the protagonist has several more drinks, sexually assaults multiple women, violently attacks several men, and destroys the DJ's equipment before running to the toilets to vomit and inject intravenous drugs, resulting in a shaky and disorientated vision.[13] Later, at a strip club, the protagonist drinks more alcohol while watching nude dancers, and eventually breaks into and steals a car to bring one stripper home to have sex. Finally, after they have sex, a look in the mirror reveals the protagonist to have been a young blonde woman; as the song ends, she passes out on her bed.[14]

Liam Howlett noted:

There's a realness to that video. Most people have had nights out like that, off their head on coke and drink … It's not to everyone's taste, but not everything we do is. No radio station was gonna play the song, so we thought we'd make a video that no one would play either.[15]
