It's now called Flash Fiction which Wikipedia defines as:
a fictional work of extreme brevity that still offers character and plot development. Identified varieties, many of them defined by word count, include the six-word story, the 280-character story, the "dribble", the "drabble", "sudden fiction", flash fiction, and "micro-story".
For example, I wrote this six word poem.
Everyone is capable of writing flash fiction. Give it a try. You might surprise yourself what you come up with.
