In the context of the U.S. Air Force and military aviation in general, the term "firewalled" typically refers to pushing the engine throttle(s) to their maximum power setting. When a pilot "firewalls" the throttle, it means they are applying full power to the aircraft's engines, often in a rapid and deliberate manner.
Pilot1: "I had that fuckingMiG firewalled!"
Pilot2: "I'm glad you got him!"
