...... not knowing an acronym

I recently received a comment on one of my earlier posts about eyebrows that meet in the middle, declaring it to be BS. Unsure of what this meant, I looked on one of my recently discovered websites www.acronymfinder.com. Unfortunately, the site returned 199 entries for BS, so I was left wondering which one to choose. I originally thought that it could mean British Standards, however, that doesn't fit grammatically, as the BS must be adjectival. Therefore, bright and shiny seems to be the correct interpretation, although I might disagree about the blog entry being shiny. Talking of bright and shiny, this is quite funny. I have not seen or read anything about the source, but I assume it is irony.
