I don't stutter, but when I'm talking about something I'm especially interested in and thinking really fast, I start talking and then stop suddenly. I do a lot of one-word sentences: l-- you-- But--. And I so a lot of arguing against myself: It's like--no, it's not like that--but it sort of fits.
When I get really worked up, like in a confrontation or argument or something, I get really tongue-tied and I have to really struggle to get every word out: I.... just..... feel..... like.... you're not..... not..... not l-l-l-listening. I sound like a really slowed-down version of Porky Pig. When that happens, my brain mostly shuts down, too, so it's hard to think.
