  • Wait... why would this word be tagged "stiffness"? What am I missing?

    November 11, 2007

  • It's a degree of stiffness: IE a small degree!

    November 11, 2007

  • I'm not thinking about this.

    November 11, 2007

  • But... but... ?! I still think it's a weird tag.

    I think flaccid is an alsome word. It's way better than flabby.

  • It might make more sense if there were other words tagged "stiffness," but this seems to be the only one.

    For some reason it reminds me of a snippet from This is Spinal Tap:

    "It's like, 'how much more black could this be?' and the answer is none. None more black."

  • I'm going to make it my mission to tag some more words with "stiffness"---possibly completely at random.

    November 11, 2007

  • Or, you could resolve to make the stiffness tag somewhat useful rather than random, and tag everything that isn't stiff. Though it does seem a pretty good tag for random purposes. It will cause some head-scratching. ;)

    May I suggest tagging baculum? Nevermind, I'll do it myself. :)

  • Way to make things more interesting, SoG!

  • pronounced like "accident"

  • I have always pronounced this to rhyme with "acid", and I see that the New Oxford American Dictionary acknowledges both pronunciations.
