Other forms: bored; boring; bores
If your friends fall asleep every time you open your mouth, you might be a bore — someone who makes the people around them bored.
In 1738, Voltaire wisely wrote, “The secret of being a bore is to tell everything.” But the word bore is less boring than you think, since it can function as both noun and verb. You can bore a hole into something by drilling through it with a tool, and you can also bore people by being excessively dull, repetitive, or tedious to be around. And don't forget the bore of a needle or gun barrel, which is the same as its diameter.
