Knowing way more than anyone should know about cartoons.
Being easily amused.
Trying new things.
Harry Potter, A Song of Ice and Fire series, Dragonlance series, Harlan Coben's works, random Star Wars books, White Wolf and other RPG based books, a variety of psychology books. I like to read, but it has been a long time since I have had time to read anything other than a text book.... Slowly making my way through The Wheel of Time series though.
Fighter, American History X, Fallen, Seven, Boondock Saints, Troy, Silence of the lambs, Hook (I know kid movie but w/e), Star Wars, most Kevin Smith stuff, Lord of the Rings, X-Men Origins Training day, Montey Python, Love Stinks, Sixth Sense. Dark Knight, The Departed, Sucker Punch, Hangover, Role Models.
The Shield, Night Court, Walking Dead, Dexter, Penn and Teller Bullshit, Family Guy, Naruto, The Boondocks, Higurashi, Venture Bros, Robot Chicken, Death Note, Game of Thrones. Sons of Anarchy. Stand Up Comedy, especially Louis CK.
Bad Religion, Within Temptation, Offspring, Sublime, Papa Roach, Smashing Pumpkins, Linkin Park, System of a Down, Tantric, Avenged Sevenfold, Disturbed, The Servant, Skindred, Slipknot, Finger Eleven, Sum 41, Dropkick Murphys, game/anime soundtracks, Apocalyptica, Trans Siberian Orchestra, really just about anything that isn't country.
Food: All of it except seafood. Thai and Mexican food, fuck yes!
TL;DR: Nerdy fantasy stuff, all kinds of humor and anything that challenges how I see the world.
The most inappropriately humorous thing I can say in any given situation.
You have ever saved Hyrule.
You paid the iron price.
You're a jinchuuriki.
You are a Vault Dweller or Vault Hunter.
You are adventurous.
Just be forewarned, I can be very long winded at times.
