C'est bidon

The French expression "C'est bidon" is a colorful and informal way to say that something is false, worthless, or of poor quality. Its origin is quite interesting and can be traced back to the early 20th century, particularly within the context of slang and popular culture. The key to understanding "bidon" lies in its primary meaning as a 'can' or 'tin container,' often used for liquids like oil, petrol, or even wine. These containers, especially when empty, can be easily dented, crushed, and are generally not very sturdy. This physical characteristic of being hollow, easily deformable, and ultimately not very substantial likely contributed to its figurative use. Here's a breakdown of the etymological development: 1. **"Bidon" as a Physical Object (Late 19th - Early 20th Century):** The word "bidon" itself comes from 'bide' (a dialectal variant of 'boude', meaning 'belly' or 'pot') with the diminutive suffix '-on.' So, literally, a small pot or container. These were common, everyday items. 2. **Figurative Meaning - Empty/Hollow (Early 20th Century):** From the physical object, the meaning evolved to describe something that is empty, hollow, or lacking substance, much like an empty tin can. This sense of emptiness or lack of content is crucial. 3. **Slang for False/Worthless (1920s-1930s):** This is where "bidon" really takes on its modern meaning. In the slang of the early 20th century, particularly among soldiers, students, and working-class populations, describing something as "bidon" became a way to dismiss it as fake, untrue, or of no value. An empty can might look like it contains something, but it's ultimately deceptive. * **Connection to 'Bluff':** There's a strong parallel with the English word 'bluff.' A bluff is an attempt to deceive someone into believing something false, much like an empty container might bluff its contents. * **Link to 'Rubbish'/'Nonsense':** The idea that something is "bidon" implies it's mere rubbish, nonsense, or a fabrication. If someone tells you a story that's "bidon," they mean it's made up or a lie. 4. **Extension to Poor Quality/Shoddy (Mid-20th Century onwards):** The meaning further expanded to encompass things of poor quality or that are shoddily made. If a product is "bidon," it's not well-made, it's flimsy, or it won't last – much like a cheap tin container. **Examples of Usage and Nuance:** * **"C'est une histoire bidon."** (It's a made-up story / a tall tale.) - Here, it means false or untrue. * **"Ce film est bidon."** (This film is rubbish / no good.) - Here, it means of poor quality or worthless. * **"Ses arguments sont bidon."** (His arguments are baseless / fake.) - Here, it means unfounded or deceptive. In essence, "C'est bidon" captures a sense of hollowness, deception, and lack of genuine value, drawing a vivid image from the common, unpretentious tin can. It's a testament to how everyday objects can inspire rich and expressive linguistic metaphors.
