The line comes from John Wick, released in 2014, starring Keanu Reeves as a retired hitman forced back into violence after gangsters steal his car and kill the puppy left by his late wife. When asked if he is back, his controlled reply became the film's signature moment and a defining scene for the franchise that followed. Clips and GIFs of the line spread across forums, edits and gaming communities, where it evolved into a universal shorthand for returning to form, logging back in or resuming something with intent.
