Rehab was released in 2006 as the lead single from Amy Winehouse's album Back to Black and became her signature song, built around friends urging her to seek treatment and her refusing. The sung no, no, no response was the most quoted part, later winning Grammy recognition and staying widely referenced after her death in 2011. Online, creators detached that short refusal from the full song and reused it as a reaction sound for memes, edits and short videos where a character needs a clear, musical way to decline something.
