Tsk. People who write 'should of' instead of 'should've'.

Because people who write 'should of' instead of 'should've' are quite annoying, eh?

A few
Alexandra Burke - I'm not one of these people who thinks anything that isn't Swedish Post-Indutrial Thrash Folk Black Grindcore Domm Metal is hit, I quite like pop music. I even watch X-Factor. But there's something about Alexandra Burke that makes me want to smash my radio whenever she's on.

People who park in disabled spaces undeservidly - this doesn't affect em in the slightest, but it really, really annoys me when people park in the spaz-badge spots without a spaz-badge. Or, even worse, people who have a blue badge because their granny is a bit slow on her feet and use it every day.

Nirvana's "Smells Like Teen Spirit" - used to live this track, way back when I was 14. Hate it now. No idea why.

Medical based reality shows - Emabrassing Bodies, Extreme Make-over etc. Just hate them all.

I would say "The daily mail" but there's nothing irrational about that hatred.

Business speak...
"At the end of the day..."
"As we go forward..."
"Developmental opportunities..."

... and job descriptions such as:

"Waste management operatives" - bin men/women (never seen a female doing this job though, so bin men is quite accurate)

Little Britain
Is my hatred irrational? I don't know, but there are 2 reasons.
1) Its not funny
2) the way the press fawned over everything they did; heralded as the greatest human beings ever. I think I missed them curing AIDS and famine.

Probably bindun.
But I can't stand the people who flood the aisle of a plane the minute the wheels have touched down and start dicking around getting their luggage out the overhead, as if it will somehow speed up the process of creating an exit point from door to ground. There's nothing better than having some impatient tit wanting to join in the scramble while you block their way to the aisle by waiting patiently for it to clear though.

Even better if it involves a bus from the plane so as you amble onto the bus as one of the last you're one of the first off the bus and you can saunter off merrily on your way. Half of them probably have luggage checked-in anyway, which they're going to have to wait for.

Do Some Sodding Research!!
Being a military buff, nothing destroys my enjoyment of a film or TV programme when they get some details wrong.
Now I find myself consciously looking for screw-ups.
I know, sad, sad, sad.....

Some are deliberate - all the light cavalry in cherry coloured pants in the 1960s "Charge of the Light Brigade", at the director's whim.
Some are foolish - incorrect rank and address of an SS officer in "The English Patient".
Some are blatant - all the imperial officers wearing the same rank plaque in "The Empire Strikes Back".
Some are mystifying - the fantasy SS uniform worn in a German History Channel doco about Reinhard Heydrich.
Some are a complete fantasy - the History Channel doco about the black US troops that liberated a concentration camp, when no black US troops ever did so!

Some of these features have huge budgets and teams of researchers and support from recognised historians. And they get the most simple things wrong..... ignorance or indifference?

Travel Issues
Living in SE London I catch the train to work every day. This is a fairly sedate commute compared to many peoples, but what really riles me is people who, when the train has pulled into a station, hammer the 'Open' button on the door over and over. Quite simply, the door will not open until the light surrounding the button comes on you dullard, have some patience and wait.

Similarly, people who continually press the button at traffic lights in an attempt to get the lights to change quicker….Again, have some patience and wait, this does not work.

Wheelie luggage. People who use these deserve to have their hands chopped off.

Continuity errors in cartoons, especially The Simpsons. It shouldn't matter because they're just stupid drawings that make us laugh, but I still find myself screaming "Marge never went to college in the 90s! RRRRRRAAAAAAAAAAARGH!" as flecks of ghoulash hit the screen.

Lazy commuters
If I'm on the bus, I hate it if someone boards the bus then gets off one or two stops later. I'm not usually someone who's in a rush and my time certainly isn't precious, but whenever I see someone whom I feel is being lazy I become filled with a teeth-gnashing rage.

People who...
pronounce 'th' as 'f'.

People who use the phrase 'to be honest' (or it's sibling 'if I'm being honest') - because they almost certainly are not.

The news - because it's mostly opinion masquerading as fact. eg "a shocking incident occurred today". An incident it maybe, but why use an adjective unless it's about making your news programme more popular than your rivals'?

[edit] One further peeve is people who say 'baby' (eg "what's baby's name" or "how does baby feel") without using 'the' or 'your' (or other equally useful pronouns*)

*may not actually be pronouns, my 1980's comprehensive education wasn't all that comprehensive

light bulbs
'Sandettie, the bulb's gone in such and such room'

'Ok'. I grab a new bulb, remove the old one, insert the new one. FLASH!!. 'No it's ok, it doesn't matter that you didn't turn the light off again. No, the blindness is only temporary, and I didn't burn my fingers'

Yes I could check the switch, but that makes no difference in the bathroom or on the stairs.

Bloody students
They are racking up loads of debt to be at uni and then are right lazy sods who expect the staff to do unpaid overtime, just because they couldn't be arsed at the beginning or middle of term to show up to a single lecture and now that there are only a few days left until Easter break and then when I next see them it'll be exam time but they still expect me to give up the entire lecture explaining some advanced theory for those who do care and make the effort, to explain something really basic which they could find with a quick google anyway.

Lazy feckless bastards that they are.

If you can't be bothered, stop wasting my time and drop out or don't bother applying in the first place. Leave it to someone who will make the effort and get something useful out of their time at uni getting a decent degree.

Movies that require you suspend belief in the laws of physics
A damned good example of this I discovered whilst watching an episode of Mythbusters. It was a film with Angelina Jolie in it about some guild of assassins. I hadn't seen any of this movie before, but when they showed what they were testing, I nearly pissed myself laughing. Bending bullets? Seriously? Even I know from high school physics that every thing moves in a straight line unless there is some influence upon it, so once a bullet leaves the barrel of a gun, that's it; you can't get it to curve around an object.

What do they take us for? Idiots?

Oh! Hollywood... right!
