What makes your blood boil? Like what is really annoying to you?

Narrow minded people.
Racism
Xenophobia
Sexism

A stint in the Jacuzzi,

Anyone who gets annoyed to the degree you are hinting at should try to get anger management therapy.
Otherwise they may boil over altogether.

When I Am Misunderstood..(it happens to me a lot)

Injustice

It is annoying when people are completely rude to me for no reason.

Ppl misunderstanding me, back stabbers! Ppl with pathetic attitude, rude and immature girls and the freaking confusing thoughts that keeps on going in my mind which i cant figure out!!!
---thats all-- (:

Dumb people or people who act dumb. Girls who say they want
to fight me then they don't.  Annoying teachers who think they can tell me
what to do.

People in general, like fake people. Especially ones, that play both sides, and ditch you.

1. People who talk trash behind your back
2. Two faced people
3. Bullies
4. Sexist people
5. Racist people
6. People who think they're everything
7. Unfair people.
8. People who take the mick out of Touretts and OCD (I have them)

Well, these things dont get my blood boiling but it certainly annoys me...
