blow

Blow is a verb meaning to expel air from the mouth or nose, producing a stream of air, and it can also refer to causing something to move by air or to an action that uses wind or gas. As a noun, blow can denote a gust of wind, a sudden impact or punch, or a strike delivered to someone. In physics and meteorology, blowing involves airflow driven by pressure differences, and wind patterns are described in terms of blowing conditions.

In everyday usage, blow appears in many idioms and phrasal verbs, such as blow up (to explode or to enlarge), blow out (to extinguish or to fail), and blow off (to ignore or neglect). In slang, blow can refer to cocaine, a drug whose use carries health risks and legal consequences.

In entertainment, Blow refers to a 2001 American biographical crime film about George Jung, directed by Ted Demme and starring Johnny Depp and Penélope Cruz. The film is based on Jung’s life and on the book by Bruce Porter. There are songs and other media titled "Blow" by various artists across genres.

The term Blow thus has a broad range of meanings across everyday language, science, and culture, with its precise sense determined by context.
