The Thai title describes the sound itself, an onomatopoeic ping-pong for a paired bell tone that listeners instantly picture as a doorbell, service bell or game show cue. Without a confirmed source, its spread has come from short-form edits where creators need a clean ding sound effect that reads even on phone speakers. The two repeated chimes work as punctuation, marking arrivals, correct choices and light reveals without music or dialogue. That simplicity keeps it reusable across languages, because the meaning is carried by the ring, not by any spoken words.
