Is there anything worse than.....?

No there isn't...

it is unbearable

someone standing behind you draggin there nails across a chalk board while snifflinf there nose while crunching on chip

yes, facing you and crunching and a small piece of Chip flies out and hits you in the face

The sound of styrofoam rubbing. I seriously freak out when I hear it. I curl up into a ball. It's pathetic, but oh so true.

I think it is worse when they loudly discuss highly personal issues such as sex or hygiene on their cell phones. It is even worse, when they decide they want to share this unwanted information directly with you.

When they are also breathing on your neck with cold coffee breath.

Then they try to talk to you, leaning in real close like they wanna kiss you, smellin like sour cream & onion and cold coffee, so you throw up all over their face, which chain reacts them to puke in yours, thus you pass out. Waking up 20 minutes later thinking you dremt it all, but still have puke on your face, so you throw up again all over yourself!

That could be worse, i think!?

That's annoying but obviously there are worse things. Death, pain, illness, people always asking questions about The Jonas Brothers.....

Yes, someone who has hard candy in their mouths but continues to smack their lips loudly until the candy dissolves.

Who about someone who chews their food with their mouths open, r talks with food in their mouths spitting food everywhere.

Yes

Someone behind you or next to you

crunching on earwax

Yes, its 10x more annoying when you're in the cinema!

people eating chips :(
