Someone who doesn't pay child support and reads a lot of gay porno on a toilet-- that being his throne. The JB stands for jail bait, because a typical King JB gets thrown in jail about fifty times in his life. A King JB is more than just a loser, it's an uber loser.
"Hey, look at that loser."

"That's not a loser, it's a King JB!"
