Stab extremely lazy couple, reportedly, for fruit (7,4)
I believe the answer is:
prickly pear
'fruit' is the definition.
(I know that prickly pear is a fruit)
'stab extremely lazy couple reportedly' is the wordplay.
I cannot really see how this works, but
'stab' could be 'prick' (pricking is a kind of stabbing) and 'prick' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for prickly pear that I've seen before include "Kind of 11 producing fruits" , "Type of cactus" , "Edible cactus fruit" .)
