I'm not even sure what anyone is arguing anymore. Antony, Roger Spruce, you're right, of course the definition of nympho is exclusive to women, but I have heard people use it to refer to men (or men use it to refer to themselves) not because they're morons, [EDIT: or even ignorant, since I certainly don't want to put words in anyone's mouth] but because it is the closest approximation to what they're trying to get across. The purpose of language is to express an idea, and that got the job done. (Also they were among friends who knew they were intelligent, not in a professional or academic situation) Anyway, my point is, for the love of god, just let it go. We all agree that nymphomaniac is a term to describe a woman with a significantly higher-than-average interest in engaging in sexual activities.
Roger Spruce - it is absolutely pedantic to still be arguing the point when everyone knows what he meant.
Mentat: it's equally ridiculous for you to still be arguing your point. You made a joke that didn't work because you used a word completely incorrectly to make it. Instead of just going "yeah, that didn't really work" you fought them on a point you have absolutely no ground in.
Since no one is denying the dictionary definition of the term, and you guys will never agree on your opinions of people who use it in a way not in accordance with the correct and proper usage, how's about we shake hands and let it go.
(I know this never works, but I always try anyway)
Fincham: Where are you going?
Me: I have no idea
Fincham: I meant where are you sitting. This wasn't an existential question.
