Oh I forgot a couple.

In class:
Flipping my pen in the air (I've started a trend; people have tried to out-flip me and failed)
Chewing my pen. I am conscious of the fact that it falls on the floor every day when I flip it. Disgusting.

But I only chew the cap, not the whole pen.

Yeah exactly. I chew the cap. LMAO I don't chew the metal part

i feel like I have OCD sometimes. everything has to be perfect.. perfectionism

procrastination... always till the last minute.

lol, I do that too. And as Erica said, I fold it or roll it into a ball or something.

LOL, I chew my straws too. So bad that the top ends up being flat.. everyone can always tell which one is mine.

And I have a tendency to destroy my pencils. Like the end part (of a mechanical pencil). I always break it off. And then when I try to put it down on the table it rolls off because I broke that part off.. :-/

I used to bite my nails, but about two years ago, it stopped.

bad habits: (that i can think of off the top of my head)
Tapping my leg nervously
pen clicking
putting any type of writing utensil in my mouth
