While browsing around for inspiration I found this incredible list of acronyms (and Backronyms - more on this term below). I remember from one of my first trainings (way back in the day) our group participated in a "Master Mind Relay" (made popular by Project Adventure). A relay consists of all sorts of activity choices (e.g., puzzles, challenges, adventures) groups work together to solve in a certain amount of time. Solving acronyms was one of the challenges. (If you are a Karl Rohnke fan and have some of his older publications, you know he was - and still is - a fan of acronyms. Did you know, according to Karl, the term Challenge by Choice was inspired by the acronym CBC - complete blood count)
Something else I learned about at the acronym site (I love learning surprises) was the term "Backronym." I'm guessing it's been around for a while, I just haven't come across it - but I do know the idea. Basically, you create an acronym out of a word that is not an acronym. For instance, one I saw at the site: YAHOO - You Always Have Other Options (I'm sure Yahoo does not claim this slogan!)
Let me know if you find anything really good!! I'll do the same.
All the best,
