Do you have any bad habits?

I have a couple but one that stands out is that I procrastinate a lot. For example I don't think I've ever studied for an exam other than reading through notes an hour before or leaving projects to the last minute. I got by in high school but for university I really have to stop doing things like that. What about you guys?

I chew my nails. Really badly. My fingers bleed sometimes.

Ya my brother used to do that. He chews a lot of gum now instead of chewing his nails, maybe that could help. "

This,but I also bite my lips just as badly "

" @CL60: I sympathize with you. Getting hit in the head with a golf club sucks, stupid girl was at the driving range and was practicing her swing in the middle of the walkway and hit the back of my head. "

I've never studied for a test in my life. I pick at the dead skin on my thumbs, which makes my thumbs look really fucking gross, but I'm trying to stop that now. Sometimes, I bite my lip when I'm nervous. Nothing really gross though. 
 
EDIT: I also constantly try to raise one eyebrow independently of the other, when I can't actually do it. It makes me look quite silly.

When I was little, like... 4 or something, when I was done biting my fingernails I would move on to my toenails. That's pretty gross. I used to hide a trashcan in my room just to spit them back out then. D: 
 
But nowadays, I'm trying to stop the nail biting. My new bad habit is this whole "not sleeping" thing and sounding like a total ass when I meet new people. My nervous habits are the worst. I make funny noises instead of saying words. Apparently it's a riot.

Chronic masturbation. In public bathrooms.
 
No, actually i procrastinate like crazy...and i stay up way too damn late all the time.
Speaking of which i really should get to bed.

Smoking.

I speak too quickly and I psychoanalyze and profile everyone I come into contact with.

buying too many games while not having a lot of time to play them. my backlog is huge.
 
i sometimes speak faster than i can think making me pause during a sentence. i guess its something like getting chocked up.

I think I'll add some more, just for fun. 
 

• I tend to over-analyze simple things
• I tend to make fun of some of my friends a lot as a joke, and then seem like a dick to anyone who doesn't know me very well.
• I speak too fast.
• I eat chips while playing games and then wipe my hands on my pants and the couch.

I bite my nails. Gum doesn't work.

Too many to count...

Just coffee and weed, which is a vast improvement over the multitudes of bad habits I used to have.

I procrastinated a lot when I was in high school. Now that I"m in college, I procrastinate less, but I would still like to stay focus more than I am now. 

I like to bite the inside of my cheek a lot.

No. i'm perfect in every way.

Procrastination is a big one

Caffeine and junk food is probably my worst health related vice. I'm really bad with procrastination to, and like I'm sure many people are here, I can fall into a gaming addiction pretty easy. If I find a game I really like, I will play it to death.

Procrastination and knuckle cracking. Easily my biggest two.

I always have to be chewing on something. This makes me eat too many snacks. Also, chewing on my lips. 
 
I really need to chew gum more instead but I can't at work.

I have a strange habit of going onto internet forums and calling people fags. Hmm...Just kidding! 
I bite my lips almost all of the time. :( I can't seem to stop.

bah i drop bad habits like.... well a bad habit. in all seriousness though maybe cracking my knuckles? i worry too.

I tend to procrastinate a lot. 
I also murder my nails, and then the skin under them.  
I also can't help myself when it comes to brutalizing my thumb. I chew off the dead skin (and sometimes not-so dead skin) off my thumbs on the palm-side. Especially in tense situations/games. 
 
I also chew on my lip. Hmm... I don't think I ever grew out of my teething phase.
