The sound comes from the DLive channel of streamer That Welsh Git, where it was set up as an ice cream alert for viewer interactions. It borrows the familiar music played by ice cream vans and trucks, a tune designed long before streaming to attract attention from a distance. Shared from stream clips onto soundboards, it kept its alert role but also became a standalone joke cue. People still use it because the melody is instantly understood, even without context, as a signal for something sweet, goofy, or worth rushing over for.
