I HATE YOUR YELLOW-NESS.

People that pretend to past thing off as there own idea or creation when it was someone elses.

I hate babies in airplanes. OOOOH MY GOD THAT PISSES ME OFF, Or fatguys sitting next to you, anywhere.

People who are clumsy. You can never trust em'.

Small children that get in your way when you skateboard.

Teenagers that think they know every thing there is about life.

People that think that they have the facts, but really don't.

Fat people...

^ xD Fat people.

fat people i hate em a little bit

if people think they are the smartest/ i want to show them that they arent
and light at the morning that is shining in my face

I hate it when you randomly take a sneezing fit.

On the top of my list would be babies that cry or annoying chatterbox kids.
Because they're frickin' everywhere. In the movie theatre, at the mall, on planes, at cafщs... you name it: they're there. (Unless it's a R18 kinda place of course :P)

Next to that would be choking on my own saliva, which happens every so often and sends me into an irritating coughing fit.

After that would be passive-aggressive people.

And after that would either be "arty people" (those who, for example, interpret what looks like a whole bunch of dyed horse shit chucked at a canvas as being a complex and emotional manifestation of your life and obviously worth $100,000) or hipsters.

...oh and those annoying Facebook camera whore girls. Makes them think they're better than they are. They start getting attitudes and shit.
That and people who go and post hateful stuff anywhere on the internet and when people tell them to shut it, they go and say "lol come say that to my face I smash u boi" and accuse such people of hiding behind their monitors when they're doing it themselves.
