I have managed to decipher or look up just about every AFAIK, IIRC, etc., but WAG has me stumped. My best guess is Wild Ass Guess, but that is probably just my wild ass guess.
Anybody care to enlighten me?
Thanks, I knew you would! LOL!
Bingo
Simple as that, dude, although we once had a poster who thought it stood for “Wager a guess”. I thought that was quite classy.
Note to self: WAG is now bingo, not wild ass guess.
And a SWAG is a Scientific Wild-Assed Guess, that is, a WAG based on some actual knowledge of the subject.
Thanks all y’all, I have been obsessed with it for a couple of weeks, and finally had to ask. It’s the only thing I could think of, nice to know I am on the same track here!
Also, I am a dude-ette, please! 
… or a guess which uses some science, not necessarily related in any way to the actual problem or the guess.
Then there’s CWAG (completely wild-assed guess) and TWSEWAG (Totally without supportive evidence wild-assed guess) and CTPBBMGABTMSIBIAWAG (Contrary to popular belief but my great Aunt Betsy told me so I believe it anyway wild assed guess.)
Soooo, how you doin?
Ya know, you have the cutest punctuation.
I’m new to these forums and I’ve found this site essential to understanding what’s going on here…

Why limit yourself? I find an entire panel of clergy barely adequate under these trying conditions.
No pun intended, BTW. (Note gratuitous abbreviation, though.)
Huh. I thought it was “wager(ing) a guess”, too.
“Wild ass guess” somehow seems more appropriate though.
Not to be confused with a DDAG. A domestic god ass guess.
Whenever I don’t know what a fictional word means I look it up on the urban dictionary.
There’s also PORNMAG, or Playboy? Only Research, Not Muff! Arsed Guess.
I was first told that it meant Wide-Area Guess.
For Aussie Dopers, they have to sleep on it first before offering a SWAG.
