Telolet refers to the melodic horns fitted to many Indonesian buses, and the sound became widely known through social media clips of fans, especially children, waving at drivers and asking them to honk. Those short videos travelled far beyond Indonesia, turning the distinctive horn into a recognisable meme sound on TikTok and other platforms. It remains popular because the tune-like blast is instantly funny out of context, works as a surprise cue in edits, and carries the playful energy of the original roadside moments.
