What is Flash Fiction?

One of the classic books containing "flash fiction," or extremely short stories, is "Palm-of-the-Hand" stories, by the Japanese author Yasunari Kawabata. He wrote them throughout the 20th century beginning in 1920.

A "flash" is something that occurs suddenly, or in a very brief amount of time. So, a flash fiction is a type of very short story.

It's like super brief fiction. Like a short story.
