It's English slang...as in "Shut yer bleedin' gob, you fecking twit!" :-) I love English slang, and I have gotten to know a great deal of it from 2 sources...Britcoms and the Mudcat Cafe. With a reasonable masterly of British slang one can easily give the impression that one is from the UK.

As in: "Oh, sod off, you stupid git!"

Parrots sound even funnier than usual when they curse with a British accent.
