Prick

Alright, Monday in class I mentioned that I thought the dirty words used in Tropic of Cancer have changed in meaning since the time it was written. KP disagreed, and said that only twice in history have there really been changes in the English language. This is true, but I'm not so sure it applies to slang terms. I'll concede that cunt is more or less the same. My original thought, when reading, was that Miller said cunt as a desirable thing, and of course now, as said in class, it refers to a putrid vagina. I guess it was a desirable thing, but because of the fact that Miller's sick character desired said unkempt women. However, I disagree that prick hasn't changed. Obviously in today's world it is used to describe an unsatisfactory penis. I don't think Miller's narcissistic character would denounce himself in such a way, so I feel that the connotation from then to now has definitely changed. Thoughts?
