Oh boy, do I got a long list.

To name a few:

Being interrupted in certain situations. If I'm having a casual conversation with friends, it doesn't really bother me as much. In other scenarios, however, it pisses me off. In some cases, I will wait five minutes to say something and let others talk. I give a second to pause, then I start saying my piece. Second or third syllable in, someone continues on with their conversation as if it wasn't obvious I was talking. Apparently, it is okay when I have to wait a minute to speak, but it is not okay when they have to wait. It really bothers me, especially when it occurs multiple times in a row.

People who are extremely dismissive of intellectuals as being this elite and snobbish class.

People (including some popular philosophers) who think they are being clever with some special insight no one thought of before that everyone has thought of before. Bonus points if its a wordplay type "insight".

Optimistic, happy extroverts who are pushy. You happy and positive. I get it. Now get away from me.

Every thread needs a theme song.

That bugs me a lot too. Sometimes I really wonder, "was I just imagining that I was talking?" when some jerk butted in and took over the conversation as if no one had the floor.

Humorless knot holes.

Sanctimonious hypocrites.

The kind of conservative who is always saying no one wants to work these days.
The kind of liberal who is always identifying racists, sexists, and so on.

Micromanagers. (Well, really most supervisors and managers whatever they do.)

People who are like cats -- who are very picky about who they will talk to, socialize with, purr for, sit next to, have sex with, etc, and {i}especially when they condescend to grace one with their presence.[/i] Elitist snobs, in other words. I lift my leg on them.

I prefer the more egalitarian dog types.

It pisses me off when people say "It is what it is".................GRRRRRRRRRRRRRRRRRRRR

How about the double-is?

The thing is-is, that usage became fashionable maybe around the '90s. Clinton was a particularly frequent double-is-er, but he didn't invent it.

Maybe it started because people wanted to say something that sounded like an unusually awkward and difficult construction, trying for the sound of "The way it is, is that they're just going to keep that policy.", or something like that, to prove their courageous and hip willingness to unconventionally follow logic. ...but didn't want to bother coming up with such a sentence, and just lazily doubled an "is".

The double-is, isn't dead by any means. It is-is all over radio presentations and conversations.

That's an official standard utterance for Neo-Advaitists. ...but Neo-Advaita would be a whole other topic of dismay and annoyance.

It is what it is.

Everything happens for a reason. Say what you will about it, but it is what it is.

But that's obviously a truism, and conveys no information. Anyone it's told to already knew that it is what it is.

It is what it is, but that fact has no bearing on or relevance to whatever utterance it replies to.

People talking with food in their mouth.

Your reply is insufficient but it is what it is. It could've been other than what it was.

I think it would be much more surprising if they said it ain't what it is >:O

It could've been other than what it was. — Nils Loc

But it's already obvious to everyone that it isn't/wasn't.

The way my ears can hear so much better than my fingers can play.

It pisses me off when people ask how I can be a moral person if I don't believe in god.
Just as bad is when they ask if you believe in the devil when they find out you don't believe in god.

That reminds me: people who say cliche lines right out of a book in response to negative situations. Bonus points if you just opened up to them or asked them for personal advice.

Yeah, well, what doesn't kill you makes you stronger. Duh.

Noisy children and the persistently rude bitch at work, to name just a few.

Came here to say the same thing.

Someone is in love? (L) >:)

"The system is not working right now, there is nothing we can do". As if this were my problem rather than theirs.

People tailgating me on a four lane freeway. Happened again this morning. Dude if you don't like how I'm driving then pick one of the other three available lanes! And I'm not driving slowly, I'm driving behind someone who's driving behind someone. It's a freeway full of cars all going well over the speed limit to start with. Grrrrrrrr.

Haha! I see what you did there. :) Adorable you are!

Now this one I could take a liking to but it would contradict my Sunny disposition. ;)
