VIVIZ is a South Korean trio formed by former GFRIEND members Eunha, SinB and Umji, and MANIAC is the title track from their 2023 mini album Versus. The song's bright pop sound and choreography helped it circulate widely among K-pop fans on short video platforms, where short chorus clips are reused for fancams, dance covers and edits. Its recognisable hook makes it easy to drop into fan projects without extra context, which is why the excerpt keeps appearing in K-pop edits and social posts.
