All mouth and no trousers
Meaning
This phrase describes someone who talks a lot about what they are going to do but never actually follows through with action.
Origin
The phrase conjures the comical image of someone speaking grandly, all bluster and pronouncements, but completely unready for action, perhaps even comically undressed for the task at hand. While its precise origins are somewhat obscured, the expression gained widespread popularity in mid-20th-century Britain. It cleverly uses the common item of clothing—trousers—as a symbol of preparedness, seriousness, or capability. To be without them suggests a profound lack of serious intent, reducing the verbose individual to an empty shell of promises, all talk and no substance.
Examples
- He promised to revolutionize the industry, but after a year, it was clear he was all mouth and no trousers.
- Don't listen to John's boasts; when it comes to actual work, he's all mouth and no trousers.
