We set such homophones very indiscriminately at the moment of truth (4,4,5,2,5)
I believe the answer is:
when push comes to shove
'we set such homophones very indiscriminately at the moment of truth' is the definition.
I know nothing about this answer so I can't judge whether this works.
'we set such homophones very indiscriminately' is the wordplay.
'very' becomes 'v' (abbreviation).
'indiscriminately' indicates an anagram (I've seen this in other clues).
'we'+'set'+'such'+'homophones'+'v'='wesetsuchhomophonesv'
'wesetsuchhomophonesv' anagrammed gives 'WHEN PUSH COMES TO SHOVE'.
Can you help me to learn more?
(Other definitions for when push comes to shove that I've seen before include "At crunch time (4,4,5,2,5)" , "At the moment at which a decision has to be made" , "At decisive moment" .)
