The line comes from The Dark Knight Rises in 2012, spoken by Bane, played by Tom Hardy, during his fight with Batman in the sewers. In the full speech Bane contrasts Batman's use of darkness as a tool with his own upbringing inside it. The clip was shortened online into a standalone quote and spread through movie edits, reaction videos and soundboards. Its serious delivery made it perfect for parody, and it remains a shorthand for claiming deeper experience than an opponent.
