Swashbuckler, a word we use for a pirate, was created from the archaic words swash, meaning “to make noise by striking,” and buckler, meaning “shield.”
A swaggering brute yelling and banging his sword on his shield was called a swashbuckler.
These bullies were given a “wide berth,” which in nautical lingo means to anchor or berth a ship a safe distance away from another that might cause trouble.
