Pop left line, when getting absolutely nothing (3,3)
I believe the answer is:
sod all
'nothing' is the definition.
(I've seen this before)
'pop left line when getting absolutely' is the wordplay.
I cannot quite understand how this works, but
'pop' could be 'soda' (fizzy pop) and 'soda' is present in the answer.
'left' could be 'l' (common abbreviation) and 'l' is found within the answer.
'line' could be 'l' (used when specifying particular lines from a poem) and 'l' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for sod all that I've seen before include "nothing" , "duck, perhaps?" .)
