1) I wink a lot at people during conversation. I often don't know if I'm flirting with them, or if I just have a twitch.

2) I often talk to myself more than I talk to other people. I'm not anti-social, I just happen to mutter to myself under my breath if I'm left alone.

3) Blue fluff sometimes lives in my belly button. It doesn't appear when I've been wearing blue clothes, which I thought would explain it, so I've yet to discover where this comes from.

I do this.

I also constantly figit (especially when thinking and sitting down).

Combine this with the fact that I'm constantly thinking (partly because of my job, partly because of my interests), that means I'm always figiting and/or pacing (if my mind is really racing, I'll do both). When I'm at work, and my mind gets overloaded with thoughts, I often go for a walk (to the nearest coffee shop, or something), by the time I get back, I know exactly what I need to do.

I'm extremely bad at accepting authority, always have been as a child. If I can't see the "point" of a rule, I'll often go out of my way to break it.

I usually enjoy getting a song stuck in my head.

I can tend to sleep as much or as little as I want, and still feel exactly the same the next day: groggy for the first couple of hours, then extremely perky. Doesn't matter if I have 20 minutes or 12 hours.

Caffeine doesn't wake me up, tends to do the reverse (and make me need to do a number 2. Like, extremely.)

- I pretend my dog speaks and I make him say the stupidest things ever.
- When buying canned food, I will switch can if the one I picked is dented although I know the food inside the dented can is just as good.
- I chew on my pens

1. I tend to bastardize someone's name after i know them for a while.. Spurgeonryan would become spurge.. galaki will become Gal.. etc.. it's more out of laziness then anything else... heck I don't even remember the names of my students.. it always ends up me calling them.. "hey" "you" "Miss" "dude" "shortlegs" etc

1A. i think I also use less words when I know someone better.. last week I just messaged the word "beer" to some people and 99% knew exactly what I was talking about.. except my gf.. who did groceries and got some beer cans while I meant "Lets go out and drink Beer"

2. I'm constantly re-adjusting my hair...

3. i tend to call/message my friends at the last moment if they are doing something and wanna go out or do stuff with me.. which is really anoying.. cause it makes them feel sorry when they say no..

I'm the same as you when it comes to mirrors. There are a few mirrors in the house that make me look awesome and there's this on lying mirror that makes me look like crap!

I'm pretty sure that has to do with the lighting, though. My bathroom lights make me look sick, but when I go to the hallway the brighter, less yellowish lights make me look like a sexy, healthy, tanned hunk. 

At least one of those sonsofabitches knows what's right. 

I hate the feel and sound of velvet being touched, it sends shivers up my spine and makes me cringe.

Yeah.. we need pics of this.. just because..

Thought of some more:

I cannot sleep in a bed that hasn't been made, or be in a room with an unmade bed.

I have a fear of sharks (fairly normal), and they cause me to have night terrors at least twice a month. In fact, I have irregular lucid dreams... and I always immediately force a shark into the dream (almost compulsively) and turn it into a nightmare.

When I get an ulcer, they usually last for weeks and weeks, because I enjoy the pain of tormenting it. Although I always come to regret it when cleaning my teeth.

Ever since being a child I NEEDED to clean my teeth straight away when waking up, and straight before going to bed. My mouth felt unclean, otherwise (fairly normal for adults, but as a kid, this is kinda rare).

I slept with teddy bear until the age of 20. Only reason I stopped was because I moved to Hong Kong, and couldn't fit it in with everything else I needed/wanted to take... it's still waiting for me at home, though!

I love my life. My past is amazing, my present is fascinating, and my future is exciting. This might not seem like a quirk, or what have you, but it seems to me that so many people around me are just nowhere near as optimistic, and always have some issue with their life that they're not pleased with.

I rarely make eye contact when talking to people, I find it quite uncomfortable. Making eye contact to me is like how long can you keep your hand on a stove without moving.

I also have Trucks' canned foods quirk, and SamuelRSmith's overly optimistic outlook. I don't like bothering people with my contentedness, I always feel like an alien when people complain about their lives.
