As one can easily see " ---O-O--- " represents a person wearing a pair of glasses..
Literally, you mention it when you want to call someone a geek or a nerd(obviously as a term of offence). But most of the time it its just used between close friends trying to pull a light joke on each other. :)

Get the [---O-O---] neck gaiter and mug.
The o's represent eyes and the '^' is the mouth, basically this is an emote used to show derpiness and quirkiness, or a bird.

Get a o^o mug for your mom Sarah.
A facial expression used to represent a particular emotion that cannot be described by the simple means of O_O. It has a wide array of representation, for example, a longing for a particular object or simply a loss of words.
