Polyphemus,n., plural Polyphemi. An archaic euphemism for the male genitalia. ______________
To accompany the tittery-whoppet, this is the silliest euphemism for the male genitals the authors of my source found. The mythological Polyphemus was the Cyclopes herdsman from The Odyssey who killed and ate several of Odysseus' men before the hero got Polyphemus drunk and put out his eye with a sharpened stick. How the connection between a mythical Cyclopes and a bit of male anatomy was made is beyond me, but it does seem to say something about mens' wishful thinking.
From the book: "Doubtless there is an allusion from the classics denoting a crippled, half-blind midget that would be far more fitting than that of a mighty, towering, single-eyed monster, but we don't know what it is."
Personally, I think the women got the better end of the linguistic deal here. :\
