In my case it's literally just unloading an AK in Pavlov just to reload it.
No idea why

I pull at my hair literally 24/7, wish I could stop

I have a few speech habits that probably drive some people insane.

I dust my hair out for dandruff, it started way back in middle school and I never stopped.

In school I used to moan when my bullies hit me to get them to leave me alone. Now I do it anytime I get hurt and I think I made myself a masochist.

I can't stop using my pheromones on my trainer to hypnotize him into fucking my brains out ;w;

Adding a swear in every sentence when talking to my friends

I always talk about my thoughts even when it’s something normal people wouldn’t mention like my mental showdown whether I wanted coffee or tea xd that can be annoying to people I talk to

Dry fapping. I mean I have a stroker specifically for jerking off but I just sorta go straight for jerking it with my hand without lube or anything 98% of the time. Maybe it's because clean up is a lot easier.

I'm that type of chick who turns her head and half her upper body, whenever I see a video game car turn.
Like when I see a racing game, and there's a right turn, half the room is staring at me what the fuck am I doing, and why a game hit me with real G force. It is just a light habit, but I guess some finds it cute, or totally annoying. lol

Hey same! Especially on Mario Kart games

No matter what I do it must be an even amount of times, like 2, 4, 6, etc. It started in Video games, always firing 2 or 4 shots before reloading but never 1, 3, 5 etc, it then evolved to the point where everything I do is in even numbers. If I, say, accidentally hit something with my hand, I get anxious if I don't hit it at least one more time to make it even

I somehow trained myself as a kid to get confused and forget what I am talking about when I get too nervous or embarrassed. I think I did it to get out of conversations that made me uncomfortable. Now it is just annoying.

I’ve gotten a horrible habit of falling or tripping. I’m starting to seriously believe this might be early onset multiple schlerosis or something because I trip on air, I accidentally yeet shit out my hands, etc etc.

I grind my canines when I'm thinking, so now they're sharp as fuck.
