The clip comes from Shia LaBeouf's 'Just Do It' motivational video, released in May 2015 as a performance piece made with Central Saint Martins art students and filmed entirely against a green screen. Its theatrical intensity made it instant meme material: editors spliced LaBeouf into movie scenes, video games and workout videos, and the green screen invited endless remixes. A decade later it remains one of the internet's go-to hype sounds, instantly recognizable from the first shouted syllable and still quoted whenever someone needs an absurd push to act.
