The line comes from SpongeBob SquarePants, where time cards jump the story forward and the narrator reads out the gap in a flat, serious voice. 2000 Years Later became one of the most exaggerated cards, and clips of it spread widely as a meme for waiting, delays, and slow progress. Paired here with a short wow, it works as a quick reaction sound for videos, streams, and edits about something taking far too long. Its humour comes from familiarity: viewers know the format instantly and understand the joke without any extra explanation.
