I'm not really afraid to admit these kinds of things but I'll say 'em anyway.
Eating popsicles in the shower. (I'm a guy, just clarifying)
Play Magic: The Gathering, WoW, and D&D, which I miss a lot because my brother sold the guide books and they are hella expensive T_T
I like Image comics stuff: Spawn, Walking Dead
90's metal/ alt. bands: Disturbed, Killswitch Engage, Good Charlette, Cold, Chevelle, A7X, Atreyu, etc.(And Daft Punk)
Pooping.
Being the nerdiest person out of all of my friends. (I like to think of it as an achievement)
Knowing way to much stuff about movies that people don't know, and games for that matter.
The smell of burnt rubber.
The list could go on but I'll just stop there.
