The 'Backpack Kid' meme features Russell Horning, who became an internet sensation after his deadpan performance of the 'Floss' dance on Saturday Night Live alongside Katy Perry in 2017. Wearing his signature backpack and maintaining a stoic facial expression while swinging his arms rapidly, Horning created a cultural phenomenon that transcended the screen. The dance move, which involves rhythmic arm swinging behind and in front of the body, eventually led to the release of the song 'I Be Flossin,' which further cemented the meme's place in digital history. It is often used to represent awkward confidence, mindless repetition, or simply to celebrate the absurd viral trends of the late 2010s.
