[Blob] Nice one. Have you seen this clue before? My late father was convinced he was the originator. I just adapted it a little. BTW - The 3rd word is 'YOUR' which I feel is more idiomatically natural ['ONE'S' is perhaps too formal?] and besides, I wanted to use 'one's' in the clue giving 15 letters to strengthen the anagram red herring.I shall now take a break from work and give some thought to your outstanding clue, unless someone has posted the answer while I've been faffing around.

[rab] Cheers. It was quite a relief to see that some literary license *can* be taken when indicating insertions etc. It would be awfully dull if we had to adhere to a strict list of accepted words/phrases. Cavalierism is good. Can we have some more clues? I'm learning lots.

[Chalky] Heh, I doubt you'd learn much from my clues.

I once saw that clued, in a book on crosswords I once read, as
Pay attention, or a new sexual perversion? (5,2,4,4)

If this was really a crossword, then you would probably have a few letters in my clue by now - so how about ...
