I'm not exactly sure how this prompt word thing works. Last time I played this game in a writing group, we pulled words from a hat. So I, uh, wrote a 2-second python script to randomly choose a set of words from the prompts. Anywhere from 3 to 6 words. Rules say 1 to 6, but I think it wants at least 3 to be a fair kick.
The results of my first run were: 'ignorance', 'dark', 'remedy', 'open', 'impact'.
I should sign up. Gulp.
If you want to randomize:
from random import choice
words = ('list', 'of', 'words', 'here')
wordcount = choice(range(3,6))
results = 
for i in range(0, wordcount):
____results.append(choice(words)) # indent, of course
