a face like O_O but with a smile

when you're hungover as shit after a spending a night drunk as a skunk

the "o" represents the eyes and the "u" represents the upper lip being placed over the bottom one making it look like a u shape..hence ouo

An exclamation of extreme happiness.

Very annoying form of "uwu". It seems sexual but it actually used to announce one's presence. You'll feel the urge to beat up people that this CURSED ouo but you won't do so because you love them. You'll just stay strong and hope that's over soon. The retarded ouo users will die eventually.

The "u" represents the smiling genital lips of a woman when it is surrounded by a pair of balls.
