Untitled is a pop-punk ballad by Canadian band Simple Plan, released in the mid-2000s as one of the band's most emotional songs. The chorus, built around the question of how such a loss could happen, became widely recognisable on its own and was later clipped for short videos and soundboards. Online, creators adopted it as shorthand for sudden sadness or regret, pairing it with breakups, defeats and dramatic reveals, which has kept the short chorus in circulation long after its original chart run.
