There's such a wide range of answers I have for this, I'll probably come off as an irascible person or something.
For starters, the number one thing that annoys me then proceeds to drive me absolutely insane is not being able to find something when I need it. It could be a paper, or a dustpan, anything. If I require something and cannot find it in the place that it SHOULD be, then I'm prone to going absolutely mad. It is possibly my single largest pet peeve, without a doubt. Hell, it could be just something I want that I know I have. Well, basically just boils down to misplacing something anyway.
Another thing that annoys me to the point of indignation is when people think they can push me around. In reality, I'm possibly the nicest, most tolerable, reasonable person (though some people would probably think me insane, I find myself to be quite rational) in the world. I don't like being pushed around by ANYONE, for any reason, but I tolerate it anyway. Recently, I was actually pushed over the boiling point by someone, and she has never given me any kind of trouble since then, in fact, she's actually been nice to me.
Another thing that irritates me so much, I saw this through high school and I still see it today, is when people dumb themselves down to impress their friends. It's like being "smart" isn't the cool thing to do. When it is taken to the extreme where someone who has the potential to go to Harvard or some shit just makes sure they get straight C's so that they don't come off as a nerd, I just want to shake that person and ask why the Hell they are letting such potential go to waste. High school ain't that hard, the public education system is getting more and more dumbed down, and yet it's like people deliberately fail classes and shit because that's the cool thing. Personally, I think it's dangerous to society when we have a disturbingly large part of a generation dumbing themselves down just to be cool. I HATE that so goddamn much. I try not to be judgmental about it, I've been guilty of it too, but WHY IS IT COOL TO BE A TOTAL RETARD AND FAIL EVERY CLASS ON PURPOSE?
Well, those are my top three right there. The rest is just random shit.
- Waiting in lines
- Waiting for food
- people who drive in my tailpipe
- people who pull out into traffic without bothering to look, nearly causing me to slam into them with my '94 Jeep, where the only thing that spares their life is quick thinking on my part
- people on 'power trips' even if the abuse is never directed at me (though it tends to be)
- people who always bitch and complain and stuff but never do anything about it (I'm guilty of it too, otherwise it'd be one meriting a long rant like my top three.)
- people who drive like ten miles below the speed limit, and can't take the fucking hint that a train of like ten cars means that maybe they should put their foot on the gas
- people who talk on their cell phones while driving (never guilty of that, trust me, your hair appointment's going to be fine if you're a few minutes late, but it won't be happening if you accidently get yourself or someone else killed because you were making this hugely important phone call)
- people with horribly shitty sound systems where the only thing you hear is bass driving around blasting Dr. Dre like it's cool or something (kinda falls under the whole dumbing oneself down rant imo)
- people who have obnoxiously loud engines on their shitty-ass ghetto looking piece of shit, I just want to tell them to fix their god damn muffler, and that they're not cool, they're just a fucking twat
- people who think they're cool or funny, but in reality everyone fucking hates them but they can't seem to take the god damn hint
- when "That's what she said" is said by the same person constantly, you know, you'll say something that using the joke wouldn't even be funny, but they do it anyway. Well, really, it's when someone uses a very simple joke in a situation in which it wouldn't be remotely funny, they just end up looking like an idiot and annoying everyone.
- the government
- people who ignore the truth, even when it's placed right in front of them, and it completely undeniable
- Sean Hannity
- Rush Limbaugh
- Sarah Palin
- Barack Obama
- Nancy Pelosi
- Barney Frank
- hypocrites (but aren't we all guilty of hypocrisy in one way or another? I've proven that even I can be hypocritical too)
- religious fanatics
- organized religion
- public education
- airports
- going through airport security
- deliberate, dishonest business practice
- Irish flute music
- country music
- mainstream garbage-infested pop music
- people who mess with my head when I'm really stoned
- buzzkills (guilty!)
- people who hate for no reason, I don't care if you hate Jews, gays, or blacks, you have nothing to back yourself up with. Now I kind of understand if a gay guy makes an unwanted advance on you and you tell them NO but they keep doing it anyway, that shit pisses me off too.
- "Drug Free America"
- terrible singers who use this operatic tone that isn't really in tune, is horribly wobbly and just overall annoying to the point that it actually causes me physical discomfort
Uh...that's just about it. Understand though, a lot of these are in varying degrees of how much annoyance they cause me.
Edit: just remembered this one, saw it happen at Wal*Mart the other day. Being excessively obese does not qualify one to park in the handicapped spot, that is reserved for people who actually have a real disability like being paralyzed and being unable to get about in a wheelchair, not for a stupid, fat American that is too goddamn lazy to walk the extra twenty feet. Now if your excessive obesity has actually caused you to damage your legs in some way and it's painful to walk that much, then I feel sympathy for you, look, I'm the most reasonable person around, it might just be because of a real handicap that you weigh close to four hundred pounds. Eh, this is a minor one, just had to cover my bases.
