"I JUST FOUND A NEW EMOTICON BY MANICALLY PUNCHING EVERY BUTTON ON MY KEYBOARD TO CONNOTE SURPRISE," Meaghan O'Connell wrote on her Facebook wall. The Tumblr community director didn't say what type of surprise the emoticon depicts.

I'd say it's dismay, but that's well-covered by D: – except that upside-down emoticon might need a replacement.

What do you think :U means?
