Pair of idiots batting, getting knocked back and hit (11)
I believe the answer is:
assassinate
'pair of idiots' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their base form.
Perhaps there's a link between them I don't understand?
'batting getting knocked back and hit' is the wordplay.
I cannot quite understand how this works, but
'batting' could be 'in' (as in batting or being 'in' in cricket) and 'in' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for assassinate that I've seen before include "Murder (a political or religious leader)" , "Kill for political reasons" , "Dispatch" , "Kill (a VIP)" , "Kill by contract" .)
