Every English teacher you've ever had has discouraged you from quoting the dictionary and, at least when I was in school, strongly discouraged the use of Wikipedia. Let's make some history tonight and do something mildly hack-ish. How does Wikipedia define a rout?
A rout is a chaotic and disorderly retreat or withdrawal of troops from a battlefield, resulting in the victory of the opposing party, or following defeat, a collapse of discipline, or poor morale.
A routed army often disintegrates into... "every man for himself" .
