Not lifting a finger, one put in offer before the Parisian (4,4)
I believe the answer is:
bone idle
'not lifting a finger' is the definition.
(I've seen this before)
'one put in offer before the parisian' is the wordplay.
'put in' is an insertion indicator.
'offer' becomes 'bid' (bid is a kind of offer).
'before' says to put letters next to each other.
'the parisian' becomes 'le' (definite article in French).
'one' put inside 'bid' is 'boneid'.
'boneid'+'le'='BONE-IDLE'
(Other definitions for bone idle that I've seen before include "staff may be?" , "Very lazy, from the marrow out" , "Very lazy from the inside out" , "Utterly lazy, won't do a tap" , "Constitutionally lazy" .)
