Gen Y, Y Chromosome

I was thinking about setting up a friend, but I needed to do some reconnaissance. I asked our mutual friend what type of guys aforementioned friend usually goes for - frat boys?

"No, I think she used to like frat boys but now she's trying to move away from that."

OK, but what other sorts of guys are there? And then it struck me: There are only two types of boys our age (20 - 30). I put together an org chart for illustrative purposes.

That's it.

You're either one or the other. Of course, within those types you have your various subsets. My friend and I brainstormed a few. This is by no means an exhaustive list.

And there's bound to be some overlap within select groups. The blue boxes represent possible variations:
