I'm posting in the beginners section despite having ridden and maintained bikes for about 40 years because it seems modern lingo is new and unknown to me. 
I keep encountering the term BSO. The context around it usually seems to imply something derogatory. But I genuinely don't know what it means. Who can enlighten me?
