My wife and I were talking at dinner about a problem she was having with a Scrum Master at work, and our son, who was probably about 12 at the time said, “Scrum Master? That sounds like something a third-grader would call another third grader as an insult! You’re such a … Scrum Master!”
Let's register "Certified Scrumbag": a person that has no value outside scrum tasks, has no ability to provide a technical assessment on anything, has no ability to implement anything, has no ability to make a rational decision that performs better than throwing a dice.
