Mask Off is a 2017 single by American rapper Future, built around a distinctive flute melody over a Metro Boomin trap beat. The flute hook quickly became the song's most recognisable part and was widely clipped for short videos, where its light, almost playful sound contrasted with the heavy beat underneath. Creators began pairing it with unmaskings, reveals and confident entrances, a use that spread across TikTok and other short-form platforms. It remains popular because listeners recognise it within a second, making it an instant shorthand for a dramatic reveal.
