I was talking to my wife about it this morning over breakfast and gave some examples of the "frivial" claims including the very English occupation of "moat cleaning".
Realising that I had invented a new word (frivial) I resorted to our Scrabble dictionary to check whether it was indeed a word (it isn't). However, I did come up with some other interesting words which I will remember for future life-and-death games. One such word is "frowst" which means to lounge in a stuffy room. A bit like the House of Commons really.
