The line comes from Call of Duty multiplayer, where the announcer calls out killstreak rewards for both teams during a match. The AC130 is a playable gunship reward in Modern Warfare 2 from 2009, circling the map while its operator fires large cannons from above. Clips of its callout spread through gaming videos and soundboards because the phrasing is instantly recognisable to shooter fans. It remains popular as a shorthand for friendly air support, even among viewers who never earned the streak themselves.
