Breh dude was an iconic character in an iconic movie. People like the look nothing complicatedBecause Non-Black People are Clueless about Black Hair, and see something THEY "Think Is Cool" and use it.
I've never in my life seen another Breh with that hairstyle.
Plus a lot of Concept artists just copy what they see others doing.
This is just like the ‘Rachel’ from the 90s
