The line comes from the multiplayer announcer in Call of Duty 4: Modern Warfare, released in 2007, where the UAV was a three kill streak that revealed enemies on the minimap. The same style of dry callout later defined other shooters, sitting alongside lines like enemy spotted and bomb has been planted in gaming culture. Clips spread through YouTube montages, forums and soundboards in the late 2000s and 2010s, and the phrase stayed popular because any overhead or surveillance joke can borrow its instant military authority.
