Definition
A 'lock' in general terms is a device or mechanism used to fasten or secure something, preventing it from being opened or moved. It can also mean a hold in wrestling or martial arts. It's a way to keep things in place or to control movement. Unlike a key, which unlocks, a lock itself secures. Think of it as a barrier or restraint. In wrestling, a 'lock' refers to a specific hold or grappling technique used to control an opponent.
