Is roperipe an actual word, or a misspelling? It's in the M-W entry for villain,
http://www.m-w.com/cgi-bin/thesaurus?book=Thesaurus&va=villain. I thought it might be a misspelling, having just found one in Merriam-Webster: I went to their thesaurus for the word knave (I plead the 5th. Amendment on why), and found the word villian highlighted. When I clicked on it, surprise surprise, "No entries found that match villian." M-W doesn't have roperipe, nor did Google find it.
