There is a big difference between a young ignorant dude from the hood saying it to his likely limited audience compared to a +40year old Megastar with fans all over the world.
Imagine if Drake, Kendrick or Cole would start using that word in their lyrics ...Em should know better.
The fact that makes it worse is that he was addressing a actual person with it...that's quite rare these days.
Cole did use it in his lyrics.
