Black Hat 

Noun: An adventure vlogger on YouTube who travels and is often referred to as Black Hat or BlackHat but goes by the user name BlackHat2005. Although the 2005 in the name is not widely known, it is thought to be no coincidence, and a secret. This is not the case, however, the reason is only told upon request.
In addition, it is often assumed that he is in someway affiliated with the group of hackers also known as blackhat, it is said that this name is used not in attempts to copy these people, but is rather for personal reasons.

Have you seen that awesome traveling vlogger Black Hat?
