prepropositioned gets one google, it's been (mis)used before, by someone in the navy
crapparoni gets two googles, one by a very cute 17-year old somewhere in the midwest
regretable gets 5700 googles, it's a common misspelling, and this particular semantic misuse of the word is also regrettably common, as I'm sure you intended.
infomasturbatory, however, appears to be brand new. I compliment you. I hope it enters the lexicon, it's a tremendously fabulous word.
