My ex-gf learned the dances to Korean pop songs (mostly big bang).
I do a good job of hiding my geekiness in public (I focus on my other, “cool” interests like sports and cars). I never really take my geekiness to the extreme; I’m just really consistent. I carved a Ninja holding a heart out of chocolate for Valentines Day. I stayed up till 4AM the night before midterms finishing the Makoto arc of Kanon (2006). Finally, I camped out 14 hours to get a Wii on launch day.
