Fair arrests with miscreant
I believe the answer is:
so-and-so
'miscreant' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'fair arrests with' is the wordplay.
'fair' becomes 'soso' (I've seen this before**).
'arrests' means one lot of letters goes inside another.
'with' becomes 'and' (I've seen this before).
'soso' enclosing 'and' is 'SO-AND-SO'.
Can you help me to learn more?
(Other definitions for so-and-so that I've seen before include "Disfavoured person" , "Person unspecified or abjured" , "Unpleasant person - whose name has been forgotten!" , "No sodas for this unpleasant person" , "Disliked person" .)
