The code for the nerd smiley on Meebo. It is a really awesome image and can have multiple meanings. Those who know not of the power the :B possesses are foolish and unknowing beings.

There is no good example for :B, as it can be used in so many situations that one or two would just not exemplify it's usefulness.
