TOMBOY is the title track from (G)I-DLE's first full album, I Never Die, released in March 2022. The South Korean girl group built the song around a rock-influenced pop sound and lyrics about refusing to fit a stereotype, which helped it stand out from typical K-pop releases at the time. It quickly became a chart hit in South Korea and abroad, fuelled by dance challenges and short-form videos that reused its chorus. Creators still return to it because its attitude translates instantly, even in a clip lasting only a few seconds.
