A loaded sock [1] (or stocking), [2] also known as a weighted sock, [3] [4] [5] cosh, [6] [7] [8] slungshot, [6] [9] blackjack, [6] sap, [10] [11] or beaner is any common form of sock or stocking filled or stuffed with hard items to be used as a blunt force makeshift weapon, often with the intent to murder. However, these socks can also be filled with lighter items like a bar of soap [12] or wet sand [12] to mutilate or seriously injure the target. These socks might be loaded with pennies or other coins, rocks, locks, dominoes, or other hard items. One common phrase used to describe hitting someone with a loaded sock is to sock it to them, which has since evolved to mean generally winning something. [13] The colloquialism or reference term – many of them neologistic – which describes the loaded sock depends on what the sock has been loaded with. A sock loaded with one or more rocks is often called a rock in a sock, [14] or a rock sock, [15] just as one with a lock has been called a lock in a sock, [16] or lock sock, [17] this pattern might follow for any other object. [1] Loaded socks have been used in guerrilla warfare and irregular warfare for hundreds of years, such as those used by British scouts during the Second Boer War to silently kill sentries during the Relief of Mafeking. The authors of Colonel Z write that this battle was: "...another opportunity for Claude Dansey to take his loaded sock to the sentries..." [18] Loaded socks have been used as weapons during protests against police or paramilitary forces, while police forces hit back with batons. They might occasionally be used as projectile weapons. [19] Loaded socks are often used in blanket parties as part of military hazing rituals, such as at basic training, or during the Crossing The Line Ceremony of many navies. Loaded socks are also used by members of gangs and organized crime as methods of physical intimidation during protection racket schemes. [20] In the Victorian era, loaded socks with sand in them were known as sandbags, and gangs like the Peaky Blinders and the Sluggers often made use of them. [21] Loaded socks can also be used in muggings, as was done in the 1700's by filling a stocking with sand or leadshot. [22] Loaded socks have been used as forms of sexual violence and physical abuse in domestic relationships. [23] More commonly, however, loaded socks are used as forms of prison violence. [1] [24] Loaded socks in prisons are usually filled with hard items, but can also often be filled with sharp objects like blades. [25] Other prisoners might prefer loading socks with plug sockets. [26] Loaded socks are often used during prison escapes, such as the one used at New Jersey State Prison in 1909. [27] Some loaded socks are stuffed with single soup cans. [28]
