Fancy is a song by the K-pop group TWICE, and this clip focuses on its refrain rather than a full verse or intro. The track became widely used in fan edits and short-form video because the chorus is immediate, polished and easy to recognize. Online, creators often pick this section when they want a clean pop lift for transitions, dance snippets or aesthetic montage moments. Its staying power comes from how quickly the hook sets a mood, even when only a few seconds of the song are used.
