OwO is a emotion/expression. If someone said something mean to you, you say "OwO". If someone said something funny and you didn't think it was funny you stare and say "OwO". Do this and you will become AWESOME. WE WILL BECOME OUR OWN ARMY OF OwOers

An emoji similar too oof but owo is a little less rude, you use it when you don't really care if you put a word infront of it or as normal as a cute stare as you have nothing to say kind of like i-
