FEPSUDOSY

Well, this is a word I made up by using my daughter's alphabet magnets... I don't really have a definition, but I have been looking for a good one. All variations are possible - fepsudosical, fepsudosiary, that sort of thing. Please help! Example: That is the most fepsudosical thing I've ever seen! It makes me feel so fepsudosical just looking at it!
