I'm coming a little late to the party, but I recently realized that OMC is an abbreviation for Old Man Coffee, which I believe means older, conservative gentlemen playing poker. These are usually tight (and passive?) players who play in the afternoons, drinking coffee and waiting for the nuts. Right?
Similarly, I saw on a recent thread in this forum for the abbreviation "SJW," which I assume is Social Justice Warrior.
Question: What are other common abbreviations and stereotype names are there for typical players found in games? I tried searching for this, but couldn't find a list. Surely, someone has compiled a list, ja?
I recalled reading something about abbreviations on here. Here is the link to the post that I read. There are not many other abbreviations for player types.
