Given my upbringing, it's not a surprise to me that I turned out to be a prude. (My wife wants to see the new Vito Mortenson movie, the one with an 8 minute fight scene where he's nude. I'm not enthused.) Although I loosened up on language, the Internet still feels a bit formal to me (that's a combination of words not often seen). And I understand that using profanity can cause the spam filters to trip. So I normally don't.
But here's a chance to recommend a site with two long posts strictly on obscenity, of the excretory kind. I've pushed Dirk Beauregard's site before, and do so again.
