:3 is a cat face. Used as a sort of cutesy or shy smile, playful or bashful. In real life it would be expressed with a slight, coquettish pursing of the lips.

:3 represents two arms covering the mouth, as in, "I'm playfully hiding from what I said.." It is both confidence and submission to the audience.

"we should hang out tomorrow :3" implies that the comment was playful and not completely serious.
