Tahu Bulat is best known online as the catchy call associated with Indonesian tofu vendors, especially the phrase sung from moving street carts or vehicles. The sound became widely shared in memes because it is repetitive, recognizable, and easy to drop into short comedy edits. It also gained extra visibility through the mobile game Tahu Bulat, which helped introduce the phrase to younger internet users. Its staying power comes from that mix of real-life familiarity, local humor, and instant audio recognition.
