Hollaback Girl is a 2005 single by Gwen Stefani from her debut solo album Love. Angel. Music. Baby., built around a stomping cheerleader chant and its famous banana spelling. Produced with Pharrell Williams and Chad Hugo, it became one of the defining pop hits of the mid-2000s and a staple of dance routines and school-spirit parodies. Its short, chantable hook later found a second life online, where creators reuse it for hype moments, comebacks and dance edits because the rhythm and attitude are instantly recognisable even without the full song.
