  • I've been watching in fascination as this word acquires a new meaning. It's now in common use as a synonym for "very" and "extremely" (as in the phrase "Mr. Pibb + Red Vines = crazy delicious"), and I love the new meaning. I use it myself.

    The only other word I can think of that's undergone such a process within my lifetime is "random" (as in "boy, that was a random comment").

  • That's crazy interesting, ptero!

    Though I (personally) (myself) think that the combination of Mr Pibbs and red vines* sounds pretty disgusting. Barfworthy, almost.

    *: assuming red vines are what I think they are.
