Oh I have a ton of stuff to share. I hate...
-Commercials that overstay their welcome and show up twice every break on every channel.
-When I've had my eye on a really good CD box set for a long time, only for the price to raise $50 when I finally have the money.
-People of any race who complain about being discriminated, while proudly displaying every negative stereotype of their race.
-People who think Cradle of Filth is black metal, Slipknot is death metal, etc.
-When someone wears a band shirt without being able to name more than 3 songs from the band they're wearing.
-How impossible it is for me to get my first job (McDonald's hasn't even called me!!!).
-Anyone that thinks imitating Family Guy or South Park characters is funny.
-Teachers who don't realize their students have other classes (and lives).
-The fact that I'm still writing this.
-How impossible it is to find any Black Sabbath CD with Tony or Ian.
-Not having my own room.
-People who can't take a hint.
-Any type, shape, and form of a guitard.
-Hot skinny chicks who post pictures on their Myspaces saying "UGH IM SO FATT AND UGLYYYY!!!1". Shut up already, we know what you're trying to do.
I got a lot more but I think I've bitched enough.
