'cynical affection' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'copper drove pablo mad' is the wordplay.
'copper' becomes 'cu' (Cu is the chemical symbol for copper).
'mad' indicates anagramming the letters.
'drove'+'pablo'='drovepablo'
'drovepablo' with letters rearranged gives 'pboardlove'.
'cu'+'pboardlove'='CUPBOARD-LOVE'

'from' acts as a link.
