The 'Running Joker' meme features Joaquin Phoenix's Arthur Fleck from the 2019 film 'Joker' sprint-running away from a scene, often pursued by detectives or police. The image gained viral traction as a relatable reaction image used to describe situations where someone is desperately fleeing their responsibilities, inevitable consequences, or uncomfortable social interactions. Its popularity stems from the frantic energy of the performance combined with the movie's dark aesthetic, making it the perfect visual shorthand for the feeling of avoidance. Today, it remains a staple for anyone documenting their escape from adult tasks or awkward life moments.
