The line comes from the Thai film Fa Sai Jai Chuen Ban, where veteran comedian Na Khom, known in Thai as Naa Khom, delivers it in character during a comic scene. The full film has circulated on YouTube through Phranakornfilm Official, which helped Thai viewers rediscover the moment and lift it out of context. On soundboards it now works as a standalone Thai meme reaction, shared in edits, streams and group chats whenever something gross, slimy or unexpectedly shocking appears. Its staying power comes from Na Khom's voice and the way one phrase can turn disgust into a joke.
