Initially used by pirates, to form sentences such as "Yarrgh me hearties" or "Yarrgh
Jim Lad, where's me pieces of eight?", it is now used by me as a random exclamation.
In the short time that I have been using this word, I have found that it is best used to scare away little Year 7s and 8s, especially of the townie variety, that annoy me.
I imagine it would also flow well at Pirate fancy dress parties, although I cannot be 100%
sure as sadly I've never been to
one.
