Finding idle amusement when slaughter occurs? (7,4)
I believe the answer is:
killing time
'finding idle amusement' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'slaughter occurs?' is the wordplay.
'slaughter' becomes 'killing' (I've seen this before).
'occurs?' becomes 'time' (I can't explain this - if you can you should believe this answer much more).
'killing'+'time'='KILLING TIME'
'when' is the link.
Can you help me to learn more?
(Other definitions for killing time that I've seen before include "Finding idle amusement - perhaps" , "Occupying oneself to avoid boredom" , "Filling in spare moments" , "Occupying oneself to pass hours" .)
