Duuuuude, maybe you are.

My hugs are half assed hugs unless I am completely and utterly wasted because it is an invasion and I don't like to be touched.

in fucking college some of the girls thought it would be funny to do drive by classroom hugs. I'm sitting on the PC doing work, next thing you know some girl is tackle hugging me and running away laughing because of my reaction.

I hated that phase they went through.
OMG, I relate so much on the issue of hugging, I have the same thing, I hate hugs, normally, except by the rare person and even then I have to be in the mood. I have a big personal space thing and I hate it when people invade it. A friend of mine once commented that he could tell that I'd tense up as soon as people would get in my personal space and if someone tried to hug me who hadn't earned that right yet, that I would look like a stiff, my body would go all tense and my face would be HELP ME!
Apparently even when I'm wasted, my hugs can still be pretty stiff, the only times they aren't is when I'm wasted and in a really jolly mood, the sort of mood where you'll fart in a room full of people and laugh about it, yeah, that's the sort of time I'll hug pretty much anyone, but if anyone mistakes a friendly hug for a more-than friendly hug when I'm in a jolly wasted mood and then tries to get in my pants (or if I think they are trying to get into my pants) then they had better watch out 'cause I'll growl, wasted or not, I don't like unwanted advances.
I know an old lady who loves to hug me every time she sees me, I dunno, I think she thinks I'm under-hugged. So she has to hug me, and sometimes when I see her I am so not in the mood to be hugged, but hug her anyway whilst mentally thinking HURRY up, hurry up, hurry up, hurry up.
And this guy I knew in TAFE, he had a huge crush on me and loved to suprise-hug me. I hated it. The first time he did it my body just reacted and my arms went up and I accidently whacked him. He was like
whoah whoah, what's your problem, I was
just trying to hug you, and I told him
"I don't like hugs, especially not from guys," and he was like,
but we're friends, what's your problem with guys anyway, and I was like
I just don't like hugs, ok, just don't hug me. So he didn't hug me for awhile, but every now and again he'd suprise hug me and I'd be left feel awful: I'd go straight into protection mode.
