I vocal stim a lot, but mostly I just make noises. The most common one is high pitched noises, which I make for fun but also when I'm stressed. I may also repeat the words over and over again for fun, although usually they're words that I made up. When people have upset me, I would repeat, "disgusting, disgusting, disgusting..." over and over again, either out loud or sometimes in my head if I really need to hide it.
