Pirate Lingo 101
 

Depending on how your character was grown, you may have a stronger accent than others. For example myself, I was brought up as a Governor meaning I use a fair mount of Pirate Lingo but not all of it. You should atleast use 10% of this lingo no matter what while roleplaying. If you are a hardcore pirate, and sailing the seas and buccaneering is your thing, you should use 100% of the lingo. Also note this isn't a complete or even a full list of Pirate lingo, just 101, try coming up with some of your own phrases and insults if you wish, just keep in mind, keep it reasonably clean. Pirates don't use modern day cussing, they are wordsmiths, now to get sailing ye scab-picking-red-nose-biters.

I stickied this old thread.
I feel it can always help people struggling with RPing. I still want everyone to use this. Part of the rules are to be RP as a pirate. And you have to follow the rules to stay in the kingdom. So this will help some of you to be productive members in the kingdom.
