And they called it Scrum (iteration 2)
Why did they call this lightweight process (that later became know as an Agile process framework) Scrum? I don't know - but allow me some revisionist historical fiction, and I'll tell you.
Scrum by definition is a play in the real sport of Rugby. I think Jeff Sutherland (roots of Scrum) may be a Rugby fan. Being an observant guy and noticing the similarity to software development and the true game, it hit him one day in the midst of a game (it was most likely a legal hit, as there are few illegal hits in Rugby - this ain't Football).
Scrum - in Rugby: a play that commences after a pause in play (and we ain't goin' stop for just anything - this ain't Football) where the two opposing teams discuss in an orderly fashion the true possession of the ball. The outcome of this play is the start of a complex (perhaps chaotic) plan by the possessive team to reach their objective and score a goal.
Now why does software development even resemble this game? Well we do sometimes pause during development. Well not the really good teams - just the nanzy-panzy teams. But it is the beginning teams with which we must work first. The paws of which I speak are the daily breaks we take for the dog walking and the spouse's honey dew list, and resetting the alarm clock to 6:00 AM after the cat unplugged it again (rather that default to 12:00 - wouldn't 6:00 AM be a better default - wonder what their Story Test script has in that spreadsheet cell).
What it Was, Was Football (YouTube).
Andy Griffith's famous 1953 stand-up monologue about college football. It has become one of the most beloved comedy recordings of all time. The illustrations used in this video were drawn by George Woodbridge, a Mad Magazine artist.
Listen to Andy (what Dialect is that?) mentally map Football to Scrum.
