Tribal mentality.
Whites for the most part don’t have a need to be a member of a tribe and try to impress other members of the tribe by looking ridiculous, blacks do.
Not too much different than “I’ve got a bigger bone through my nose than you do” that you still see in primitive tribes.
I’ve concluded through objective observation that “cool” generally means
“that level of rebellion to societal norms just below what the majority would consider dangerous or criminal”.
But that’s the definition within those in Western Civilization. Those of “urban” culture go beyond this to allow the dangerous and criminal behavior in the realm of “cool”.
