The Firebat originated in the original StarCraft as a Terran infantry unit armed with flamethrowers, and returned in StarCraft 2 with updated voice lines performed in a gruff military style. Blizzard gave the unit short, aggressive barks for selection and combat, and players clipped individual lines for soundboards and videos. This expletive take spread among strategy fans because it captures the unit personality in seconds, and it remains used as a quick gaming reaction long after release.
