The phrase ตอบถูก simply means answered correctly in Thai, and clips like this live in the world of quiz and challenge content rather than coming from one famous show. Short confirmation sounds are a staple of user made soundboards because they give creators an instant way to reward the audience. This version has circulated as a meme reaction for trivia, classroom style jokes and guess the answer formats. Its appeal is practical, it is fast, language specific and unmistakably positive, so it keeps getting reused wherever a quick win needs emphasis.
