The second lamest smiley ever. The first is :E. Again, has no real meaning except to convey the degree of nerdness. Appropriately, it is overused by forum nerds and those who idolize them for some odd reason.

:B
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.
