Definitions
An idiomatic slang term for someone who is headstrong, ungovernable, or difficult to control — a person who talks back, refuses to be reined in, and says exactly what they think regardless of the consequences. The metaphor comes from horsemanship: a 'hot-mouthed' horse resists the bit and is hard to control, and the same quality in a person suggests wilful, opinionated, combustible energy. It's an evocative if old-fashioned way to describe someone whose mouth runs faster than their good sense.
The new recruit was talented but hot-mouthed, constantly arguing with senior officers over decisions that weren't his to question.

- give it mouth63%
A dated British slang phrase meaning to speak loudly, speak up, or give voice to something with confidence and volume. If someone told you to give it mouth, they were urging you to stop muttering and actually project — to put your words out there boldly. It sits alongside similar British expressions about speaking one's mind and can also imply boasting or exaggerating. Mostly historical now, but the expression captures a very British directness about the act of speaking up.
