... and are doing farely well on the battles.

Remember when the Olsen twins were about to turn 18? Boys, guys, and grampas were drooling all over the web. Countdown clocks to their 18th birthday were the meme of the land. But once they turned 18, all the hoopla fizzled out. So what's the big deal with girls the age between 16 and 18? What's the appeal? Is it the novelty? Is it the anticipation? Is it the taboo?

If girls below 16 are cute and girls above 18 are sexy, what are the 16-18 girls?
