The phrase comes from Dutch, where kakkerlak is the everyday word for a cockroach and can also be thrown around as a mocking nickname. As a short soundboard clip it spread less as a quote from a known show and more as a reusable reaction, shared for its happy tone and instantly quotable wording. Dutch speakers recognise the joke immediately, while other listeners pick it up from context and timing. That makes it useful far beyond its literal translation, especially in edits where a cheerful insult is funnier than a serious one.
