You guys sound like out of touch old men. "Wuh? Momo? That have pedos and little girlies in their underpants?"
From all accounts, MomoCon is a cool event. Great to see SEGA hosting panels.
As far as the name, a simple Google search will tell you that "momo" is "peach tree" in Japanese. The convention is in Georgia, peaches are the state fruit. it's not some skeevy reference to something.
