Where to start a hasty row between varsity men (6)
I believe the answer is:
putney
If this is the answer, I'm afraid I cannot explain it.
Can you help me to learn more?
(Other definitions for putney that I've seen before include "Causing an obstruction" , "Start point for varsity boat race" , "Start of today's race" , "on the Thames - with 28a" , "Starting point for university boat race" .)
