Sometimes my son will when he is generally happy and excited. He will also run and occasionally hit. More often when he was younger. He is 15 now.
My best friend laughs when something makes her nervous or uncomfortable. I think it's like a coping mechanism in this case.

Reasons for Giggling in Autism
Sensory Regulation: Autistic individuals may use laughter to manage sensory input, reacting to sounds, textures, or sights that feel stimulating or amusing.
Emotional Coping: Giggling can be a response to discomfort, stress, or anxiety, or a way to mask distress.
Internal Stimuli: An autistic person might laugh while remembering a funny moment or experience, or in response to a specific thought.
Social Communication: Laughing may be used to imitate neurotypical behaviors or to try and fit in, even if the situation isn't understood as funny.
Avoidance: In some cases, unexpected giggling can function as a tactic to avoid a task, such as schoolwork.
I sometimes get the giggles if something funny randomly pops into my head. It's definitely a welcome case of something! ๐
I would giggle at these times-If I was under a lot of stress I would end up giggling at an inappropriate time. The giggling is a release of emotion at a time when you've endured stress which kept your feelings inside and when you release those emotions it comes out as giggling. For example whenever I had an issue that caused me to be upset I would end up giggling and it would make me feel embarrassed . I've learned that the giggling is a release of the emotion and tense I felt. Just don't get angry or upset when you see someone giggle because they're not making fun or doing it deliberately.,they have a hard time showing emotion.
