A Milli is Lil Wayne's 2008 single from his landmark album Tha Carter III, built on a sparse, hypnotic beat by producer Bangladesh. It became one of the defining rap records of the late 2000s and won the Grammy for Best Rap Solo Performance in 2009. Years later the track found a second life as a TikTok trend sound, where creators, including Spanish-speaking users posting millonarios-style flex content, use its relentless energy for money montages and confidence edits. Its minimal beat and quotable hook keep it instantly recognisable.
