It's okay to laugh at ring toss? (4,4)
I believe the answer is:
fair game
'toss?' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
I don't understand the remainder of the clue.
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" .)
