Pocket Sand is when sand or other granular objects are kept in the pockets for use in self-defense. If a person using pocket sand is in a confrontation, they can draw the sand from their pockets and use it to temporarily blind or distract their opponent. There is an online community of people interested in the uses and deployments of Pocket Sand.
Pocket Sand was the invention of Dale Gribble, an amateur survivalist character on the popular television show King of the Hill. In the 2001 episode titled "Soldier of Misfortune," (Season 6, Episode 106) Dale is fighting with a man and yells "Pocket Sand!" before taking sand from his pockets, throwing it in the man's eyes, and running out of the room.
In 2004, the term was defined on urbandictionary.com.
In 2005, the website pocketsand.com was registered as a place "for those who are dedicated to pocket sand." The site featured only a GIF of the King of the Hill scene and a link to potential merchandise about pocket sand.
