I didn't know (or didn't know I know) the adjective order thing (not that I'm a writer). Not that I think the 'rule' is as rigid as suggested. Nor did I know until recently that there is an underlying rule of vowel order in ablaut constructions, namely -i-, -a-, -o-, eg Bish bash bosh, tick tock, hiphop, ding-dang-dong, ping-pong, flim-flam, mish-mash etc. Though I suppose it makes sense, as the tongue moves from the front to the back of the mouth.
