Any "reality/talent" show. Isn't TOWIE scripted? I tried to watch it once and I swear I dropped 10 IQ points in the opening titles alone. And things like The X-Factor, just gets more irritating every year.
Twilight fans - love the books (so far, on the third) and the movies.. Aren't the best adaptations but they aren't the worst either. But the people who wear t-shirts that say "Team Edward" or "Team Jacob" annoy me. And I genuinely saw a group of girls aged about 14 stood outside Boots the other day spraying themselves with body glitter, babbling about looking like a Cullen. Really?!
Stupidly high heels. You can't buy a nice pair of shoes to go out in that shouldn't come with a health warning and built in airbags for when you fall over. I know that makes me sound old, but I'm not. I'm 22 and just really uncoordinated without making stilts part of the equation.
Any woman TV personality. Cheryl Cole, Holly Willoughby, Katie Price, the Loose Women lot, Lorraine Kelly, Cat Deely, Kate Thornton (I think she might be the worst), can't stand the lot of them.
The culture of compensation. If someone pushes me out in front of a bus, yes, they are responsible. If I trip up in the street and graze my knee, my first though is generally, "get up, you plonker," not, "must write to the council, there was no sign there, no barrier around that ever so slightly raised slab, it's their fault, THEY WILL PAY!" And we wonder why insurance premiums are so high. Some things are just accidents/unfortunate.

The Olympics. Waste of money. And I want Pointless back on TV please.
