Anyone with the initials "JB" are instantly cool. If they happen to have a fancy name all the better. Examples include James Bond, Jack Black, Occasionally Justin Bieber etc. These people are usually held in high regard, as the superior initials for nicknames over others such as a TJ or PJ. These are people you want to know.

Oh wow he really is the real JB.
