Wikipedia:Articles for deletion/Ass to mouth
I am 100% unsurprised that medical and psychological researched turned up nothing. However, cast your eyes over the net and you will see thousands (Google says millions, but let's be realistic) of uses of the term. With this much weight of evidence, to argue  is arguing semantics. The term is not unverifiable but by dint of what it is "respectable" sources won't mention it. Remember, Wikipedia is unusual in that it is uncensored
