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 don't know anything about this answer so I can't judge whether it can be defined by this definition.
'we set such homophones very indiscriminately' is the wordplay.
'very' becomes 'v' (common abbreviation).
'indiscriminately' indicates anagramming the letters (I've seen this in other clues).
'we'+'set'+'such'+'homophones'+'v'='wesetsuchhomophonesv'
'wesetsuchhomophonesv' is an anagram of '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" .)
