In North Korea "grooming" refers to randomly placing some spoiled little fat kid in charge of the entire North Korean military ahead of all the four star generals after you have a stroke and realize that you aren't the immortal demigod that you once thought you were.

This isn't meant as a jab at your comment, I just think it is really funny that anyone including his father would think that he is capable of running a country. On the other hand I guess he can't do much worse than dad.
