In a magazine we bought owen I happened upon a list of "exclaimations" that Thomas the tank engine might say (through the medium of ringo star) in sticker form. Happily many of them can easily sub in for swear words and so could form the basis of a new sub culture. Ambitious I know, but let's give it a shot at least before we give up on the whole idea. So here they are, I shall attempt to put each one into a suggested sentence.
1) "bust my bufffers" - oh bust my buffers this is hard
2) "cinders and ashes" - cinders and ashes, what was that...
3) "burst my boiler" (on reflection very similar to bust my buffers)
4) "wheels are wizzing" - my wheels are wizzing
Any suggestions to add to the list gratefully recieved. Happy swearing!
