That's "Aristotlers". "Aristotle" is rhyming slang for "bottle", which is short for "bottle & glass", which is rhyming slang for "fuck in the arse". Thus, Aristotlers are buggers. This is all explained by Robert Graves in his amusing essay "Lars Porsena". He in turn needed to have it explained to him, discreetly, after he happened to mention Aristotle while conversing in a pub, and was indignantly told by the proprietor that that sort of language wasn't allowed there.
