"No johns" means that you can't make excuses. It is the perfect counter argument to anyone who is making any type of excuse whatever. When someone makes excuses or tries to make excuses, they are "johning". If this occurs, tell them "NO JOHHNZZ".
Me: "Dude, I just 4 stocked your Marth with my Pikachu.
n00b: "Yeah, but Marth isn't my main character."
Me (as well as crowd): "NO JOHHNZZ SON"
