The line comes from a Brazilian internet meme audio that circulates as a short WhatsApp-style voice clip, where a woman dryly notes that someone 'precisava fazer check-in' — needed to check in.

Its staying power comes from versatility: the same flat line works for any situation where preparation was the whole problem.
