The phrase comes from everyday German playground and street slang, where deine Mudda jokes have been a staple insult format for decades, similar to your mum jokes in English. This short recording spread as a shareable soundboard clip rather than from a known film or song, and its appeal is its plain delivery with no effects or context. Online it is used mainly in German speaking meme communities, gaming voice chats and short video edits, where the familiar insult structure makes the meaning clear even to viewers who catch only a few words.
