The Euthanasia Coaster is a conceptual art project designed in 2010 by Lithuanian artist Julijonas Urbonas, intended as a theoretical steel roller coaster designed to kill its passengers through cerebral hypoxia. The design features a massive 500-meter drop followed by seven loops of diminishing diameter to maintain lethal G-force. On the internet, the image became a viral symbol of dark humor, often used to represent 'the ultimate ride' or as a hyperbolic reaction to minor inconveniences and existential dread. It is frequently paired with captions about life’s downward spirals or the desire for a dramatic exit from mundane situations.
