historical usage of bust

Historically bust is derived from a dialect pronunciation of burst and is related to it much as cuss is related to curse. Bust is both a noun and a verb and has a wide range of meanings for both uses. Many are slang or informal. A few, as “a decline in economic conditions, depression,” are standard.

Where does or bust come from?

The phrase or bust may be associated with hitchhikers who’d write it on the signs they’d hold on the side of the highway while waiting for someone to offer them a ride (e.g., Vegas or bust), but the expression was apparently first popularized in the Colorado gold rush of the mid-1800s.

Following the discovery of gold in what is now Englewood, Colorado, people with little or nothing to lose began heading to an area of the state known as Pike’s Peak Country hoping to strike it rich. Around the 1850–60s, some of these dreamers began using the phrase Pike’s Peak or bust as they boarded up their homes and headed west through unforgiving weather and terrain—all for that sweet, sweet gold.

These gold-seekers didn’t invent the phrase, though. It’s recorded as early as the 1830s. Bust itself is a variant of burst, and or bust implies that one will violently break down or fall to pieces before giving up on their goal.

During the 2016 Democratic primaries, some die-hard supporters of the progressive Democratic candidate Bernie Sanders started an effort called Bernie or Bust. Some of these people pledged that they would not vote for Hillary Clinton if she won the Democratic nomination. Instead, they would write in Sanders, vote for a third-party candidate, or not vote.

How is or bust used in real life?

The phrase or bust follows the object of one’s ambition, such as a location or accomplishment (e.g., Austin or bust or 4.0 GPA or bust).

Or bust is often still used in the context of a trip, especially road trips. Nowadays it’s mostly used for enthusiasm and not meant to suggest that not arriving at the intended location is an actual possibility.

The phrase is also often used outside the realm of travel, and is meant to suggest that there is only one option and way forward, that anything else is defeat or failure (e.g., Our team is going to the Super Bowl or bust).

More examples of or bust:

“It’s win or bust for both Donegal and Roscommon at The Hyde after their opening Super Eights defeats and Bonner was making sure he had his troops rallied ahead of the long trip home to the north-west.”

—Michael Scully, Irish Mirror, July 2018
