I don’t know about that.
Since 2009, way before social media, I've seen all kinds of people saying the same thing about dude. On here, the barbershop, Twitter, IG, around the way, etc. I think people really just don’t connect with dude. He has his fans, but I can't remember the last time I saw this many people calling a rapper "boring".
You see people calling MC's wack and trash, all day. But "boring" isn't exactly an everyday critique when it comes to MC's. But Cole has kept that label since the very beginning. Dude is just boring, lol.
