The line comes from Valve's Portal series, first released in 2007, where Aperture Science sentry turrets speak in a sweet voice performed by Ellen McLain. The turrets greet, threaten and apologize to the player while trying to shoot them, creating the series' signature dark humor. Clips of their polite lines spread through gaming forums, machinima and later short video edits, where this forgiving quote became a favorite. It remains popular because the contrast between a weapon and a gentle reassurance fits betrayals, accidents and mock apologies online.
