I just learned about vagueposting; it isn't new — the term dates back to 2011 — but 2026 is when it took over. According to Know Your Meme, it evolved from vaguebooking, a Facebook phenomenon that goes all the way back to 2009. Zari Taylor, a digital culture researcher at NYU, puts it best:
“It allows everyone who’s interacting with it to place their own definition or guesses on what the person’s talking about.”
The perfect example? Tamara went viral after buying 365 buttons as her 2026 rebrand — and refusing to explain why.
