Whether you’re studying for an exam, improving conversation skills, or writing headlines, this guide will make the idiom stick.
A Funny Mix-up
Idioms can be confusing when taken literally. Imagine an English learner picturing a company “swimming upside down” — they might ask, “Do businesses actually turn over like fish?” That mental image is exactly why idioms are both charming and tricky.
Here’s a lighthearted scenario people often experience: a new learner hears someone say, “Their startup went belly up,” and pictures employees trying to flip a boardroom back upright. The literal image is amusing, but once you learn the meaning, it becomes an easy and memorable phrase to use.
What does “go belly up” mean?
The core meaning of “go belly up” is simple: a venture, company, or plan stops operating because it has failed — often implying bankruptcy or collapse. The image behind the idiom is a fish floating on its back, belly facing up, motionless and lifeless. That striking visual helps the phrase stick in your mind.
Origin and background
The idiom likely comes from nautical and fishing imagery. When a boat capsizes or a dead fish floats on the surface, the belly faces upward. Over time, speakers used that visual metaphor to describe businesses or projects that had metaphorically “capsized.”
Register and usage
This is a casual, idiomatic expression common in American English. It is well suited to conversation, journalism, and informal writing (like blog posts). However, it’s usually avoided in very formal documents like legal contracts or academic papers, where neutral terms such as bankrupt, insolvent, or ceased operations are preferable.
Example sentences
Seeing the idiom in different contexts helps you internalize its use. Here are practical, natural examples you can adopt or adapt:
- “After investing all his savings in the market, Tom’s portfolio went belly up.“
- “The small family restaurant went belly up after just one year.”
- “The coffee shop’s profits declined and the business eventually went belly up.“
- “The company’s new product line failed to attract customers and the venture went belly up.“
- “The startup’s funding dried up and it went belly up within months.”
Try rephrasing the examples to practice both idiomatic and literal styles:
- John’s dream of becoming an entrepreneur went belly up after his startup failed. (idiomatic)
- John’s startup failed and he could no longer pursue his dream of becoming an entrepreneur. (literal)
- John’s entrepreneurial aspirations were dashed after his company declared bankruptcy. (formal)

Mnemonic tricks help idioms stick. For “go belly up”, use this simple visual:
- Picture a fish floating on its back in a quiet pond — motionless and clearly finished. The belly is pointed upward.
