What does jab mean?
A jab is a quick, sharp poke, thrust, or punch. The verb commonly describes thrusting a finger, hand, needle, or other pointed object toward something in a brief, emphatic movement. In boxing, a jab has a more specific meaning: a fast, usually straight punch delivered with the lead hand, often used to test an opponent’s guard or establish distance. As a noun, “jab” can refer either to a quick poke or to the boxing punch. The word often conveys speed and sharpness rather than the sustained force associated with a stab or blow. It appears frequently in expressions such as “quick jab,” “left jab,” and “right jab,” while figurative uses can suggest a brief interruption, sharp criticism, or sudden attempt at something.
