The phrase comes from TikTok's club meme slang where klurb is a deliberate misspelling of club. The short version trims the audio to just the hook, which helped it spread as a quick punchline for party content in late TikTok edits. Creators use it to signal that everyone in the frame belongs to the same wild, welcoming crew. Its appeal has lasted because the line works as both a caption and an audio meme, instantly readable even for viewers who missed the original trend.
