Whoop whoop pull up is the spoken alert from an aircraft ground proximity warning system, designed to warn pilots they are closing too fast on terrain and must climb immediately. The alert is familiar from cockpit recordings and aviation videos, including footage of Concorde and other airliners, where its urgent rhythm makes it instantly recognisable even to non-pilots. Online, editors stripped the short warning from longer cockpit audio and reused it as a punchline for close calls, fails and sudden saves, which is why it still appears in gaming clips, driving videos and reaction edits today.
