The Eight Gates come from Naruto, the anime and manga series created by Masashi Kishimoto, where taijutsu users like Rock Lee and Might Guy release chakra limiters for extreme strength. The third gate, the Gate of Life, became a fan favourite moment from Lee's chunin exam battles and spread through anime edits, AMVs and soundboards. It is often paired in collections with other Naruto clips like the Mangekyo Sharingan, and its short shouted delivery makes it easy to reuse as a universal anime power up cue long after the original episodes aired.
