Weird Tics - the strange stuff we do without realizing it

so I was actually typing a post earlier, and I realized I'd said something along the lines of "X is pretty cool, yo".

it sounds completely ridiculous, and I don't talk like that IRL usually. or so I thought. When I actually THOUGHT about it, I realized I actually DO say that a lot, lol

so hey why not ask other people? What kind of weird stuff do you notice yourself doing?
