::::::P.S. a Google search for 'santorum anal' now produces 63,000 web pages. Though undoubtedly many of these are comments on the fact that 'santorum' has been proposed as a neologism, rather than independent uses of the neologism, I think it is impossible to argue that a new word mentioned on 63,000 different web pages does not have significant currency. To cite a comment above, 63,000 web pages is not compatible with a neologism being 'barely notable'.
