Matt Horner is the captain of the Hyperion, the battlecruiser at the centre of Jim Raynor's fleet in StarCraft II, and this line comes from his in-game dialogue. Short character voice lines from the game have long been shared as soundboard clips by players who recognise Horner's steady command style. This one endures because it is instantly understandable even outside StarCraft, working as a general reaction to a job done smoothly rather than only as a game reference.
