Online, the quote became a major meme in the late 2000s as fans remixed the “over nine thousand” moment into videos, forums and reaction edits. It stayed popular because the phrase is simple, loud and easy to apply to any situation involving extreme numbers, exaggerated hype or mock-serious power scaling jokes.
