shaver
An electric tool used to shave hair from your body.
A shaver is a young boy, especially one who's still small or just learning his way in the world. If your grandfather calls you a “young shaver,” he's using an old-fashioned, affectionate term that suggests you're still growing up but already showing promise.
Today, people rarely use the term except playfully or in older books, where you might read about a “little shaver” getting into mischief or a “young shaver” running errands.
The word also refers to an electric device that removes hair from your face or body. An electric shaver uses small, rapidly moving blades behind a protective screen to trim hair close to the skin without the mess of shaving cream. Many people prefer shavers because they're quick and convenient for daily grooming.
