'do lovers' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'ply samaritan for change?' is the wordplay.
'for change?' is an anagram indicator (I've seen 'for change' mean this (I've seen this in other clues)).
'ply'+'samaritan'='plysamaritan'
'plysamaritan' anagrammed gives 'PARTY ANIMALS'.
