Weird Tics - the strange stuff we do without realizing it

I don't think I have a mild case of OCD or anything, though - I've taken psych courses and done a little research, and people are very clear on OCD being about intense feelings of anxiety, and fear that if you don't perform your rituals then there will be direct negative consequences, not about the rituals themselves. It's an anxiety disorder. So, I don't really know what I have. Just weird little habits, I guess.

IIRC, the phrase for that is "compulsions," minus the obsessiveness. And the disorder. I think there's a few mental disorders that are pretty much normal human tendencies exaggerated to the point where they're detrimental to one's well-being, OCD and OCPD being among them.
