Would someone explain what the third gender (for marketing purposes) is to me?

Yeah, so as you can tell by the ever-widening gap between the posts on here, shit's been hectic lately.

So the other day, after taking care of the usual business and some campaign stuff, I started poking around on the Facebook fan page. What, you haven't been yet? Oh, well. It'll give you something to glance at before you dig in to The Sims Social for the next eight and a half hours. Don't look at me like you don't either. I can tell.

They are re-doing the insights, or breakdown of your fans and the page's traffic. Spiffy, I thought...it's not like they aren't re-doing everything else, every other week.

So I take a look, and no real big surprises. Not exactly ready to bust out the Spinal Tap reference about having a selective appeal just yet, but the marketing equivalent of "fuck, I needs to get on a treadmill." The majority of my fan base is between 25-44, I skew more heavily toward men, my viral numbers are promising (never knew I had viral numbers) and wait...what's this?

Wait, what? I'm no math expert here, but shouldn't that equal 100%? If fifty-four percent of my fan base are men, and thirty-nine percent are female, could somebody in Facebookland explain to me just what in the bluest of fuck the other seven percent are?

I mean, any one one the following would at least be accepted as an attempt:

• Three-boobed chick from Total Recall
  
• Post-op malpractice litigant
  
• Ya got both
• Whatever that shrill Nancy Grace thing is
  
• Too small to tell
• Undecided
• Awaiting test results like that South African runner
• Goat person living under a bridge
