I like it as a geeky dating name (X & Y chromosome), and given how its X (female) 4 Y (male) (yes yes I know that's not technically accurate but we're talking marketing here ppl) it could be a good twist on the dating site idea - woman looking for men!
I'm sure it has a ton of other application thats just what first came to mind ...
Anyways, if you could find an existing dating site provider who was looking to build out segmented interest / demographic sites I think it'd be a really catchy name and you should be able to get mid to high $XXX/'s for it.
