I never knew that Goosnargh was actually a real world until I read about ‘Goosnargh chicken’ in the Sunday Times today. I blame Douglas Adams in So Long, And Thanks For All The Fish:
‘Goosnargh,’ said Ford Prefect, which was a special Betelgeusian word he used when he knew he should say something but didn’t know what it should be.
I suppose I should’ve suspected something, given that I’ve read The Meaning of Liff, which interestingly enough is completely online, although without the funny illustrations.
