The Tracksuit Joker meme features an edited version of Joaquin Phoenix from the 2019 film 'Joker,' swapping his iconic purple suit for a casual tracksuit, often associated with Eastern European street culture. This variant gained popularity on platforms like Reddit and Twitter as a way to portray the Joker in a more relaxed, 'Gopnik' light, blending high-drama cinema with low-stakes casual wear. It is frequently used to represent moments of unbothered confidence, 'sigma' energy, or the feeling of being a casual menace to society. The humor lies in the contrast between Arthur Fleck's psychological intensity and the mundane, sporty aesthetic of the tracksuit.
