Just been thinking about the 'Let's Go Brandon' ordeal and noticed Brandon's full name, Brandon Brown.
I can't imagine the B2/BB is a coincidence but can't point to anything specific yet.
Brandon also has a degree in 'Communication' which is odd for a NASCAR driver:

Board search tool didn't show any discussion so thought I'd throw it in here whilst I dig.

Any ideas?
