Put it immediately after the confusing English line in your edit, then follow it with the Bruh Meme sound for a second reaction, and finish with the Fail Sound Meme sound to close the joke.
Über diesen Sound
This 7.5-second clip is a spoken French question, 'Where did you learn English?', delivered as a direct challenge to someone's English. It sounds pointed and teasing, with the awkward humour of calling out a strange accent or a mistranslated phrase in front of others. It works as a quick, knowing jab when language goes wrong.
