1. When I play League of Legends and a guy with no kills and a shitload of deaths call me a noob when I have clearly, much better stats than him. Afterwards though I tell everyone in the game and we gangbash him.
2. I also hate it when people talk on and on about things they know and that they want to share with us when we simply do not give a shit. You know how annoying that is? I end up agreeing to it just to make the person shut up.
3. I hate it when a bunch of people (fanboys mostly) attempt to make someone look like god, I mean, when you kiss ass, at least get a room. It totally ruins the person's image for me.
4. Lastly, for now, I hate it when people talk to you when you really don't want to talk to them. All I wanna say is "Bitch please, I don't even like you."
