Going on bold, exciting, and exotic adventures is swashbuckling. The stories of the heroic outlaw Robin Hood involve a lot of swashbuckling.
You can use swashbuckling as a noun or an adjective, so you might dress up as the swashbuckling Inigo Montoya from the movie The Princess Bride, or try to convince your friends to watch a movie full of adventure and swashbuckling. Swashbuckler came first, a 16th-century name for a swaggering fighter. Earlier, such a character was simply called a swash, which also meant "fall of a blow."
