Bill Bubba search won't give you the right result. In US it is just a proverbial term for something that Hillary Clinton called 'deplorable', arguably the comment that lost her the election to Trump. It was the start of the anti-ellite movement.
The phrase is used by many, especially one of my fav authors Bill Bryson in the book I'm a Stranger Here Myself.
Haha thats good to know, I was getting Bill "Bubba" Bussey and thinking what's the relevance of this guy? I get the reference now, thanks for clearing that up.
