Avast! - Stop and give attention. It can be used in a sense of surprise, "Whoa! Get a load of that!" which today makes it more of a "Check it out" or "No way!" or "Get off!"
Aye! - "Why yes, I agree most heartily with everything you just said or did."
Aye aye! - "I'll get right on that sir, as soon as my break is over."
Arrr! - This one is often confused with arrrgh, which is of course the sound you make when you sit on a belaying pin. "Arrr!" can mean, variously, "yes," "I agree," "I'm happy," "I'm enjoying this beer," "My team is going to win it all," "I saw that television show, it sucked!" and "That was a clever remark you or I just made." And those are just a few of the myriad possibilities of Arrr!
Beauty – The best possible pirate address for a woman. Always preceded by “me,” as in, “C’mere, me beauty,” or even, “me buxom beauty,” to one particularly well endowed. You’ll be surprised how effective this is.
Bilge rat – The bilge is the lowest level of the ship. It’s loaded with ballast and slimy, reeking water. A bilge rat, then, is a rat that lives in the worst place on the ship. Since bilge rat is a pretty dirty thing to call someone, by all means use it on your friends.
Bung hole – Victuals on a ship were stored in wooden casks. The stopper in the barrel is called the bung, and the hole is called the bung hole. That’s all. It sounds a lot worse, doesn’t it?
Grog – An alcoholic drink, usually rum diluted with water, Water aboard ship was stored for long periods in slimy wooden barrels, so you can see why rum was added to each sailor’s water ration – to kill the rancid taste.
Hornpipe – Both a single-reeded musical instrument sailors often had aboard ship, and a spirited dance that sailors do.
Lubber – (or land lubber) Lubber means, a big stupid, clumsy person who is too stupid to sail. A lubber is someone who does not go to sea, who stays on the land. Lubber is ALWAYS an insult.
Smartly – Do something quickly. “Smartly, me lass,” you might say when sending the bar maid off for another round. She will be so impressed she might well spit in your beer.
Scurvy - a disease caused by lack of vitamin C, sailors often got it for lack of citris fruits aboard their vessels. Scurvy came to be an insult meaning worthless and weak: "Avast, ye scurvy dogs!"
This may help me in case of making comunication with native people ・∀・)<ThankU I like this one , "Arrr!!!" This may have the same mean in Japanese too.
You might be surprised when it becomes important to speak like a pirate. For example, drinking heavily with your old friends from college -- by 3:00am you may start using some pirate slang ...
