This song finds Timberlake describing the flooring feeling of spotting his former girlfriend out with a new man. He addresses his former flame by telling her, "I'm out for the count. Yeah girl, you knock me out." Other boxing metaphors that Timberlake utilizes on the club banger to describe his emotions at seeing the girl with another guy include, "you've been swinging after the bell," "hit the mat," and "below the belt." To cap it all, JT also includes a beatboxing breakdown.
The song's music video was helmed by skater-turned-director Ryan Reichenfeld (Steve Martin's "Jubilation Day"). Justin's bitter girlfriend is played by Riley Keough. The model and actress is the daughter of singer-songwriter Lisa Marie Presley and the eldest grandchild of Elvis and Priscilla Presley.
