Do you love the thrill of a terrifying rollercoaster or the risky challenge of doing dangerous tricks on your skateboard? Then you're a daredevil, someone who is recklessly adventurous.
A daredevil loves adventure and excitement and tends not to think much about the safety or wisdom of their actions. The man who walked on a wire between the towers of the World Trade Center was a daredevil, and the woman who was the first to ride a barrel over Niagara Falls was also a daredevil. This word is also used as another name for a stunt performer who attempts risky tricks in front of a live audience.
