I think the point Dama was trying to make is this: how come Scott got the "Scooter" nickname simply because his name is Scott? Plenty of people named Scott are never, ever called Scooter. It's not particularly clever, or funny, or witty...it's just something taken for granted these days, but no one really knows who started it, or why.
The question that really needs to be asked is who originally had the idea to call a man named Scott "Scooter," and was it even funny at the time of inception. Maybe then, Dama's mystery would be solved. Until then, we'll simply never know.
