Snowball fight? (4,3)
I believe the answer is:
cold war
'snowball fight?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for cold war that I've seen before include "East West tension" , "State of tension and hostility" , "State of hostility (rather than hostilities?)" , "Intense hostility between nations without actually fighting" , "State of tension after 1945" .)
