In all seriousness, there are many things I hate. I know hate is a strong word, that's why I'm using it.

I hate:

Whining
Complaining
Girls screaming (think Girls Gone Wild, WOOOOOOOO, or sorostitues)
People beating on shit out of rhythm (in class on a desk, or whatever)
Politics. It's the same old shit. People who love to argue and get no where.
People who call more than once.
Old people who are set in their ways and won't die off.
Hookers who I have to ask where my ****ing money is.
Fat people. Moreso chicks than dudes.
Religion.
