Simple enough thread: what pisses you off and why?

One that comes to mind quickly are people that don't know how to use turn signals and this one is split into two parts.

1. The people that don't use turn signals
2. The people that only use their signals as they're turning

For the first one, I just hate these people.  I mean really, can you not be that bothered to move your hand two inches to turn on your turn signal?  It's a common courtesy to the person behind you, to the person by you when you're changing lanes, and to the people wanting to turn onto the street.

But those people are only really a minor annoyance, the ones that really piss me off are the people that turn on their turn signal as they're turn.  The above people are rude but the people that turn their turn signal on as they're turning are just fucking stupid.  They know what a turn signal is, they know they're supposed to use it, they just don't realize what it's for really.  That pisses me off.

Every person I see turning and then turning on their turn signal I just want to give the finger to but I really don't want to get shot.  That would be a bad thing and probably piss me off too.

Is that you from beyond the grave George? =P

Whiny spoiled kids piss me off. You know the type.

when people honk their car horn to express anger

Girls talking about Twilight........ever since the movie it seems like an epidemic.

people who honk their horns at learner drivers because they stall at the traphic lights!!! COME ON!!!!!!! give them a break! I'm sure we could give those honkers a hard time laughing as they strugle with duel analogue controles!

hahaha stop looking at the ground fool! *slaps fool on the back of the head* hahahahaha how do you like that fool! muahahahaha go on blow your self up with a grenade! MUAHAHAHAHA.... any way

I also dont like it when passangers in cars stare at you at traphic lights. and when they sit there smiling at you its even worse! on if they drive up beside you and just sit there and look at you! Its happened to me like 3 or 4 times now and its so anoying!

I also dont like people who pull up at a traphic light in the outside lane (which ends like 100 meters after the lights) in an attempt to start off really fast and cut in front of you before their lane ends. Thats anoys me like you wouldnt believe! thoes guys deserve a race! or being blocked off!

Blocking crazy drivers is one of my favourite driving past times! There is nothing more I want to do then prevent an irate driver from cutting infront of me and getting to where there going any faster then I'm going. pushing in is just mean!

I think that wraps it up for my driving hates :D

People asking me why I'm vegetarian. Fuck off, yeah.

People who are, or try to be , positive and upbeat all the time piss me off big time.
Moreover, these are the very people who snap at the end due to all the bottled up disappointments, so im also wary of them.
The second thing i hate is an over-enthusiastic pet dog, performing tricks as if trying to justify its very existence.

Oh yeah

Guys who come in and steal the girl youve been working on for the last 4 hours!

People who don't eat meat.

If animals didn't want to be eaten then they wouldn't be delicious.
