Etymology

The word "blowout" combines "blow" (Old English blāwan, meaning "to expel air") and "out" (Old English ūt, meaning "externally"). Originally describing physical bursts (e.g., tire explosions), it later expanded metaphorically to uncontrolled releases (e.g., oil wells) and celebratory events (emphasizing excess). The hair-styling sense derives from the "blowing air outward" action during drying.
