Reading an account of the big boxing match in the paper this morning I was introduced to the word 'fistic'.
I reached for my Chambers and sure enough found it listed as a facetious usage along with 'fistiana'
et al.
Which made me wonder when it is that facetious idiom crosses the line of respectability enough to be listed in the big red book?
My ancient Welsh grandmother called handkerchiefs 'hankinponks'; my old father-in-law made up various words, e.g. 'problems' became 'prombles' and in our house we have 'poik', a cross between poke and point, and 'xhuhx' an expression of mild dislike or disgust.
I'm sure you clever wordy types have similar examples - it would make for cheery reading to hear of them.
