Someone mistaken for having a large carbon cockprint, but who desires union with his muse, and would be ill-thought-of or endure public humiliation to accomplish as much.
-- So, as to be expected, the peanut-gallery dismisses his efforts as creating a large carbon cockprint
-- as only motivated by gratification, as unable to see any other dignity or value in his efforts.
-- Yeah, but really, he's a Manchester.
-- Meaning his muse is flat-chested, like a man, but he loves her anyway?
-- No, and, she's not, but, rather, that 'chester' comes from 'castor,' which is Latin for camp, and 'castor' is also connected to 'beaver' which is a euphemism for vagina, so that 'Manchester' is both a man's anal cavity, and signifies that he loves his muse so-much as like that SNL character who assumed a pose of being gay so-as to be her roommate, so-as to be with her.
-- Ah, so he would even be thought to be a 'Manchester,' (or a-hole
then), in the hope that he'll get to meet her.
