Teenage Dirtbag was released in 2000 as the debut single by American rock band Wheatus, written by frontman Brendan B. Brown about a high-school outsider fantasy. It became a sleeper hit, topping charts in Australia and reaching the top five in the UK and Ireland while finding a slower cult audience in the US. Two decades later it exploded again on TikTok, where the confessional chorus soundtracked glow-ups and storytimes, joining nostalgic song memes like Running in the 90s that refuse to fade.
