Pocket sand is a running gag from King of the Hill, the animated sitcom centred on Hank Hill and his Texas neighbours, where Dale Gribble is the paranoid, conspiracy-obsessed exterminator. Rather than fight fairly, Dale keeps sand in his pocket to throw into an opponent's eyes, shouting as he does it, a cowardly trick that fits his scheming personality perfectly. Clips of the moment circulated on video sites and soundboards, and the short, shouty line became a handy shorthand for a cheap sneak attack, keeping it popular in meme edits long after the show's original run.
