'''Serious Business''' is when a story revolves around an activity where a sizable portion of the in-story population takes it ''far'' more seriously than they should. If something's popularity rivals that of [[Elvis Presley]], [[The Beatles (band)|The Beatles]], or [[Michael Jackson]]; or if there are mainstream ''schools'' devoted to it instead of teaching reading, writing, and arithmetic, it's '''Serious Business'''.
It's often a [[Silly Reason for War]], and can turn a casual conversation into a heated [[Cavemen vs. Astronauts Debate]]. Frequently "opposed" by the [[Cavalier Competitor]]. Compare [["Stop Having Fun!" Guys]]. For the saying that "[[The Internet Is Serious Business]]", see [[GIFT]]. Related [[I'm Not Here to Make Friends]].
