Whenever I am around people I say random words that are either inappropriate or random. It usually happens when I'm nervous, excited, and sometimes when there is an awkward silence in conversations i have. Sometimes i can control them and keep saying them inside my head, but other times i blurt it out with no control. Usually people ask me why I do it and i say i dont know. I even use to do this as a child. I instead would make cat noises. My old best friend said i did it often around people. I always did it and still continue to do it. Even my kindergarten teachers said i made random noises.
