<3

This has many meanings.
Some common ones are Less than three <3, a sideways heart <3 (normally meaning love), and a face <3.
The < is the eyes/eyebrows, in a.. well, happy position. Kinda. And the mouth, 3, is like an animal mouth. Kinda.
Such as :3, =3, ;3, and so on.
But basically, whether a heart or a happy face, the meaning usually comes out as love or happiness.
Ad more threes and exclamation marks to show that the emotion is more.

Less than three <3 and more than one >1

: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. It is often seen in anime or when someone is being cute.

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