A strange and out-of-control hairstyle which has literally taken on a life of its own. Results from too long without having a haircut, characterized by unsettling feeling overcoming bystanders. A Black Swan Problem may or may not have the ability to exercise mind control over the "wearer" and invariably causes a vacant and confused look in the eyes. Although difficult to describe, one is immediately aware when they are in the presence of a Black Swan Problem.
Wow Barge, I realize I haven't seen you in a while, but that is some Black Swan Problem you are rockin.
Jesus, if you know what is good for all of us, you will get that Black Swan Problem tamed before it achieves world domination!
