Earworm

Origin

Imagine a tiny, persistent invader burrowing into your brain, not a physical creature, but a relentless melody that simply won't leave. This vivid image gave birth to the German word 'Ohrwurm' in the mid-20th century, a term combining 'Ohr' (ear) and 'Wurm' (worm) to describe that universally annoying phenomenon: a catchy tune stuck on an endless loop in one's head. The Germans, with their characteristic precision in language, perfectly captured the parasitic nature of such a tune. English speakers, lacking a similarly evocative phrase, adopted this brilliant loan translation directly, giving us 'earworm' and finally a name for that maddening, repetitive musical guest.
