Angry dismissal received when they approach fallen angel (2,2,3,5)
I believe the answer is:
go to the devil
'they approach fallen angel' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'angry dismissal received' is the wordplay.
I cannot quite understand how this works, but
'received' could be 'got' ('get' can be a synonym of 'receive') and 'got' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'when' is the link.
Can you help me to learn more?
(Other definitions for go to the devil that I've seen before include "become corrupt" , "Become ruined, away with you!" .)
