We have two quotes I like to explain bogyism:

I could not find the meaning of bogyism for the life of me. But when I saw the word I had to laugh out loud. It reminds me of a small child that can’t stop picking their nose.

They have a disease.

It’s called bogyism!

or alternatively…

A bogyism is saying something in the style of Humphrey Bogart. “The only reason to have money is to tell any SOB in the world to go to hell.”
