Please don't downvote me. I am not a native speaker. But I still don't get it. Someone care to explain ;-)
FarmVille.
As a non facebook user, I didn't get it either... :)
I use Facebook (sometimes), played FarmVille and Farm Town up until this January, and I STILL didn't get it right off. Guess pulling out of those games was a good idea after all. :)
My co-worker just told me his mother is level 137 at Farmville :) Apparently she spends 6 hours a day playing it...
The first 10 times I read this comment, I thought it was a pun on facebook's color scheme, until I realized that it's cornflower blue, not cauliflower blue.
