Yeah, I mean he's only worn the same sweater as Biggie Smalls, and rapped his lyrics on multiple occasions at pressers but there's just no way he decided to use the nickname "Notorious" because of any influence from Biggie Smalls.

He applied for copyright in regard to the nickname. Not sure if it went through because (shocker I know) there was some silly notion that he might have trouble being granted copyright because of its association with Biggie Smalls.
