The phrase is Dutch for what have I done wrong and the clip is associated online with a student named Deason and classroom humor, with the name Pieter also tagged on the original post. No widely known film or show source has been established for it, so its spread comes from soundboards and short reposts rather than a broadcast scene. Its appeal is the classroom situation itself, which translates even for listeners who do not speak Dutch, and it keeps circulating as a reaction for being blamed, questioned or singled out unfairly at school.
