Aura has long been used in anime and games to visualise a fighter's energy, shown as flames or light surrounding the body during a charge up. Online, the word took on a second life as slang for charisma and presence, especially in aura farming edits where a cool pose is treated like a power up. This short burst fits that joke perfectly, giving editors a clean audio cue for transformations, entrances and confident moments without needing dialogue or music to explain the shift in energy.
