Example: My girlfriend and I had just gotten back into our apartment. We were taking off our coats. As I went to sit down on the chair to take off my boots, she tossed her coat onto the chair. I gave her an affronted/amused look. Because we found the situation amusing, she then made a throwing gesture towards the chair and said "fwoosh" to imitate the coat flying over the chair.
Now, people I know do this sort of thing all the time. It's a quick re-enactment of something humorous, typically in a physical way, and is accompanied by a simple sound effect and mime of the event. It seems to be a way to capture the humour of an event that passed by quickly.
Is there a word for this?
