The phrase comes from Transformers, where Optimus Prime uses it as the Autobots' call to action before they move out together. It became one of the franchise's most quoted lines through the animated series and later films, and fans have reused it for decades as shorthand for teamwork and determination. Online, the short clip spread through soundboards, reaction videos and edits, where its familiar heroic tone lets creators signal that something big is about to begin without needing any explanation.
