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

o__o 

1. Similar to the emoticon o_o but with an extra underscore (_).

Upper case Os are used more often to denote more shock than lower case Os.
Generally used in the same fashion (shock, look of bewilderment, blank stare, skepticism, or weirded out). However, the extra underscore is added to denote more stronger emotions.
2. Also may be used when an o_o may not want to be repeated.

1. Person 1: I found out I was adopted
Person 2: o_o

2. Person 1: And that I'm really a robot
Person 2: o__o

Person 1: It all came to me when I fell off a cliff and into a girl's house
Person2: O__O
