"SugarCrash!" is a hyperpop anthem by Canadian artist ElyOtto that exploded on TikTok in early 2021. The song's frantic beat and high-pitched vocals became the soundtrack for a "glitchy" aesthetic and chaotic video edits, often representing a state of sensory overload or intense excitement followed by an inevitable burnout. The meme captures the essence of internet subcultures and the Gen Z "hyper-focused" mentality. Users typically pair the imagery with captions about excessive caffeine, gaming marathons, or the overwhelming nature of modern digital life, turning the catchy tune into a symbol for manic energy and the crash that follows it.
