Crossanized?

I had an interesting witnessing encounter. A person identified themself as "Concerned Christian Now Liberated" (not the shortest handle on the planet). They seemed vaguely Christian, although doctrinely weak.

Finally, he said he was "Crossanized". I've never heard that particular label. Nor have I read anything by Crossan. I have seen a couple of his books at the library (you know, the storehouse of apostates and heretics). I will have to read one of these books.
