Three little letters seem to cause such a fuss. Here is a list that I will add to as my brain spits out new words and phrases to fit the acronym. When I get enough for a table or two, I will post a new article. (Be afraid, be very afraid.)

I invite others to submit their O.S.R. words, please submit them in the comments, in three word groups in order as seen in my examples below. NOTE: It doesn’t have to relate to RPGs, or at least not in an obvious way.
