Ewelme: The smile bestowed on you by an air hostess.
Liff: A book, the contents of which are totally belied by its cover. For instance, any book the dust jacket of which bears the words. 'This book will change your life'.
Meathop: One who sets off for the scene of an aircraft crash with a picnic hamper.
Peoria: The fear of peeling too few potatoes.
Scraptoft: The absurd flap of hair a vain and balding man grows long above one ear to comb it to the other ear.
Thrupp: To hold a ruler on one end on a desk and make the other end go bbddbbddbbrrbrrrrddrr.
Ventnor: One who, having been visited as a child by a mysterious gypsy lady, is gifted with the strange power of being able to operate the air-nozzles above aeroplane seats.
Yarmouth: To shout at foreigners in the belief that the louder you speak, the better they'll understand you.
