o//o 

A face, similar to ^//^ and/or >//< . The o//o is a blushing face, however the eyes are open in shock or disbelief. This is not usually used as a positive way of blushing, such as ^//^ would be. o//o is usually used when someone is embarrassed or surprised.

Mom: I threw you a surprise birthday party, and invited all your friends, but they only had bright pink balloons

Me: o//o
