Parlay: The Pirate Code?
Surprisingly, there's little historical evidence linking the word parlay (or parley) to real-life pirates. Seafaring scallywags occasionally followed a loose code of conduct, but it seems the Pirates of the Caribbean film series popularized this reinvention of parlay.
Whatever it was called, there's no denying that pirate code is freaking cool. You'll be speaking like a grizzled sea captain after reading this list of pirate-themed words!
