Avast ya lubber, and lay up! Yah need a good floggin because of the filth coming out of your groghole! Shiver me timbers and splinter me yard arm!!! The pirate dictionary says:
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!
Now all you bilge rats say Arrrrr! NO MORE of that "belaying pin in the bung hole" arrrgh dribble! We be proper pirates after all!!!
