For words and phrases, I find "I know right?" to be extra annoying. I think the reason why is because there is this one kid I know who never says the 't' in 'right', so it ends up sounding like "I know rai?' . Also, when people want to say "I couldn't care less" but instead say "I could care less." Oh, so you do care about whateveritisyoudon'tactuallycareabout?As for horrible noises, that squeak you sometimes get if two fabrics are rubbed together. I cringe just thinking about that. Of course, there's the 'fork scraping against plate' noise, as well. I nearly claw my eyes out every time I hear that. Which is pretty much every time I eat.
