The phrase who goes there is a classic guard challenge, familiar from films, games, and comedy sketches where a sentry confronts an unseen visitor. Online, the short zap version has circulated as a meme sound for reaction edits, gaming highlights, and short videos, where its brief length makes it easy to drop over an entrance or reveal. Its appeal comes from that instant recognition: viewers understand the joke without explanation. Because the clip is short and punchy, it continues to appear whenever creators want a quick, playful interruption rather than a longer scene.
