The line comes from the Halo first person shooter series, where voice actor Jeff Steitzer has served as the multiplayer announcer since Halo Combat Evolved in 2001. His callouts mark key shifts during matches, including gaining or losing the lead against the opposing team. Clips of the announcements later spread through gaming videos, streams and soundboards alongside lines like bomb has been planted and enemy spotted in other shooters. The phrasing stays popular because it sums up a sudden reversal in a few instantly recognisable words.
