It’s the same as those bros driving around F-250s when all they ever do with it is go to town to stop at the grocery store and QuikMart and would be better served by a Camry or Prius.
People want to feel like they’re qualified/good/badass in some way or another, so they don the trappings of those who they view to possess those qualities, because they think having those superficialities makes them a part of that group (“If I do MDI things, I’ll be as good as an MDI player!”). In reality it just looks like silly overcompensation.
