Arrrrrr, today be talk like a pirate day. I thought I'd help you out a little bit with some phrases that you can use to sound like a pirate. You're going to need to buy your own rum, get your own ship and pirate clothes, however.
Some pirate phrases you can try today -
Thar she blows! – When you see a whale, not sure you'll actually see a whale today though
Shiver me timbers! – Oh my god
Scallywag – use it as an insult
Hornswaggle – to trick someone out of their money or belongings
Landlubber – someone who can't sail. They're also slow and clumsy.
Scurvy dog – another insult
Cleave him to the brisket – cutting someone across the chest. From shoulders to the stomach
Dead men tell no tales – don't leave any survivors
Or you could just sing the theme song from the "Pirates Of The Caribbean" ride at Disney and call it a day.
