But as I'm from the "if you can't beat 'em, join 'em (then destroy from within)" school, I'm actually going to act as its advocate herein; that is, at least as BS relates to communication.
My father regarded good BS every bit as much an art form as he did the illustrative work for which he was commissioned—perhaps more so.
In Southern Utah where he grew up, it was never enough to say, "He caught a fish." No, you had to dress it up a little: "The way that poor bastard was wrestling with that goddammed line you'd have thought ol' Ahab had Moby Dick on the other end instead of a guppy…"
BSing wasn't to be taken seriously, just a means of flavoring up a story: The H. Morton to the conversationalist's palate. It also became part of dad's business repertoire. Work days were a series of matinee performances with dad ingratiating himself to customers.
Affecting good humor, he'd slapped them on the back, inquire about their family (always circumspect about the pregnant teen trying to kick her habit), compliment their good taste (invariably, a nod to their choosing to do business with him), and ask who they liked in the upcoming Monday Night Football game (a sport he was so categorically dismissive of that upon receiving an autographed photo from an appreciative Jack Youngblood in the mail, his first words were, "Who's this?").
