To my calculations, this randomizer has 5.55906057e15 possibilities. Every 11 space phrase is possible to see on here, but unlikely. VERY UNLIKELY. It's a 1/5559060570000000 chance that you'll get the phrase "random word", which you start out with so don't get exited.
If you get a repeated word, CONGRATULATIONS, you're luckier than most! As of writing, I have 41700 random words in the lost, and not one match.
