A phrase used to describe something or someone that is completely useless. The literal translation is 'as useless as a motorcycle ashtray'. Motorcycles don't have ashtrays, so the analogy emphasizes the pointlessness or uselessness of something.
Examples
- Spanish: Este gadget que compré es inútil como cenicero de moto, no sirve para nada.
- English: This gadget I bought is as useless as a motorcycle ashtray, it's good for nothing.
