The word 'nub' is not anything offensive unless said in an offensive way, I doubt Beef was trying to offend anybody by saying that. Friends tend to call each other these names in a playful way, and I believe that's what Grayson was trying to do. If Gray would call him a rude word, I understand, however 'nub' is just a playful way of calling a friend. I don't think much will be done about this, as Gray hasn't broken any rules by calling a friend 'nub'. It's fine, I believe.
Hai Ender. While I appreciate your concern Beef and Zero have a long relationship as acquaintances. I will tag Zero to see if there is any real concern on his part. @Zero_Inzanity
I've provided enough time here. Should zero decide this was offensive to him he can make his own report.
