It's okay to laugh at ring toss? (4,4)
I believe the answer is:
fair game
'toss?' is the definition.
Both the answer and definition are singular nouns.
Perhaps they are linked in a way I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for fair game that I've seen before include "Legitimate object for attack or ridicule" , "permissible target" , "coconut shy?" , "person open to criticism" , "Hoop-la may be" .)
