Sweat (A La La La La Long) is a reggae song by Jamaican band Inner Circle, released in the early 1990s and later a major international hit thanks to its catchy chorus and laid-back groove. The opening line, 'I've been watching you,' introduces the song's flirtatious theme and has become one of its most quoted moments. Online, creators lift that brief vocal alone for short reaction clips, memes and social edits, where its familiar melody instantly signals playful attention or a light-hearted crush.
