Etymology

Origin of blowout

First recorded in 1815–25; noun use of verb phrase blow out

Explanation

When something stops working or breaks down, you can call it a blowout. The blowout of a city's electrical system can be a particularly big problem. A blowout most often involves air or gas pressure — a blowout when you're driving on the highway is a popped tire. You can also use the word to mean a really easy victory in sports, like your favorite football team's blowout victory over its rival. Yet another meaning of blowout is a fabulous party: "Let's have a blowout to celebrate your twenty-first birthday!" The original, colloquial American meaning of blowout was "outburst," or what might today be called a "blow up."
