The public demonstration of one's nerdiness.

This can be accomplished in various forms: clothing (costumes, game/anime related t-shirts, etc), bringing your favorite console to the university center and challenging onlookers, or simply speaking about things that are obviously meant to be private, such as WoW and what happens in /b/.
