Warframe is a free to play online shooter by Digital Extremes, and Cephalon Cy serves as the blunt, no nonsense Cephalon who commands the player's Railjack. His lines are written as short military callouts, and this one has been clipped by players for use outside the game as an enemy spotted alert. It spread through streams and soundboards, where Warframe fans use it as a Twitch redeem and non fans borrow it as a clean, instantly understood warning that something is approaching from behind.
