The line comes from Grand Theft Auto San Andreas, released in 2004, during the mission where CJ and Big Smoke chase a moving train on a motorcycle. Big Smoke's angry instruction became famous because the mission itself was notoriously hard to complete, and players shared their failed attempts online for years. Clips of the exchange later spread through gaming videos, reaction edits and meme pages, where the quote was reused whenever someone failed to keep pace. Its lasting appeal lies in that shared frustration, making it shorthand for falling behind.
