Video games, mostly World of Warcraft lately, building and playing on computers, psychology, some anime, Futurama, Family Guy, South Park, DDR, Karaoke Revolution (or Karaoke in General), Inuyasha, etc...
Someone who has a lot of common interests with me, who's cute and who thinks I'm cute. People who aren't fake or superficial, who want similar things out of life as I do. I usually go for skinny/slightly muscular guys, but what really counts with me is a strong, intelligent mind.
Punk, alternative, rock, and some pop, occasionally techno, rarely country, even more rarely rap or R&B. My favorite bands include, but are not limited to: A Perfect Circle, Breaking Benjamin, Cold, Godsmack, Hawthorne Heights, All American Rejects, Blueline Medic, Lagwagon, Armchair Martian, Badastronaut, Verbow, Samiam, Matchbox 20, Nickeback, Tool, System of a Down, and many more...
Spiderman 2 is one of my favorites, the Kill Bill series, As Good as it Gets, The Matrix (I like the first one the best), Fearless, Silent Hill, The Lord of the Rings trilogy...
Heroes was practically made just for me, it's my favorite show! Six Feet Under was a great show when it was still on HBO. Futurama, Southpark, Family Guy, Simpsons (though not so much recently), Aqua Teen Hunger Force, Inuyasha...
The entire Dragonlance series by Margaret Weis and Tracey Hickman, The Lord of the Rings, The Lord of the Flies, Just Another Kid, Farenheit 451, Dante's Inferno, 1984, the Ravenloft Series, The Death Gate Cycle, Just Another Kid, The Forgotten Realms (especially the Avatar Trilogy), and anything psychology related. The most recent book I read for fun, rather than for school, was The Light of Other Days, by Stephen Baxter, which was awesome.
I have a hard time listing a hero, probably because having a hero is a form of idealism, and that runs counter to my realism.
