The clip is identified in its file information as Eugeo's Enhance Armament moment from Sword Art Online Alicization, the arc centred on Kirito and Eugeo in the Underworld. In that story, Enhance Armament is the command swordsmen use to release the memories stored in a weapon and unleash its special ability. The phrase became recognisable to fans through the anime's battle scenes, and short clips of it now circulate as a shorthand for a power-up. It remains in use because the two-word command is instantly understood by Sword Art Online fans without further context.
