Portal 2, released by Valve in 2011, introduced defective turrets as comic relief in the Aperture Science test chambers. These faulty units have different voice lines from the standard turrets, sounding cheerful and delusional instead of cold and efficient. The I'm a bad man line became a favourite clip online because it sums up that personality in two seconds. Players share it in gaming edits, reaction videos and meme compilations, often applying it to characters who think they are intimidating when they clearly are not.
