Smoking on planes

The definition of inhibited is "unable to act in a relaxed and natural manner because of self-consciousness or mental restraint". The definition of hibited, by some, is the opposite of inhibited meaning "able to act relaxed and in a natural manner".
I was on a plane a little time ago and on the entertainment screen it read, " Smoking is strictly pornhibited". Pornhibited? So what does that exactly mean? We know what "porn" means and we know what "hibited" means. I did look through all the movies that were playing but found nothing that would allow one to smoke while watching a "movie" in a relaxed and natural way .
 I guess it was just a typo and smoking was strictly prohibited. Or maybe not? Megan?
