I get elongations and blocks.. but my worst are when I get stuck repeating a sound. It's very.. uncontrollable when it happens? Like My jaw just opens and it jerks repeatedly, making the sound until I mentally make myself stop saying the word.. If I try to say the word again too soon, it happens again. I'm always reminded of it when I see the Spanish version of hahaha 'jajajaja' because that is LITERALLY what it feels like and J and G sounds tend to be a favorite trigger. That's my most hated stutter, but I have blocks and elongations too. Mostly I do repeats.. but those broken record moments are always embarrassing. Thankfully, I've had service jobs all my life and can. not. shut up. if you get me talking about the right subject.
