You Know You Like It is a song by AlunaGeorge, the English electronic duo of singer Aluna Francis and producer George Reid. The track built its reputation on a minimal beat and a memorable sung hook, and a later DJ Snake remix helped push the song to a much wider international audience. Online, the short vocal section became detached from the full track and reused as a standalone reaction sound for edits, reveals and dance clips, where the confident phrase works even without the rest of the song playing underneath it.
