The phrasing comes from military aviation brevity, where 'bandit' means a confirmed hostile aircraft and clock positions give direction relative to the speaker. Callouts like this became familiar online through flight sims, military shooters and combat footage breakdowns, where short directional warnings keep comms clear. As a standalone soundboard clip, it works because everyone recognises the urgency even without context. Editors keep using it to fake tactical comms over gaming clips, airsoft footage and scripted skits.
