A bigot rolled with rugger match in disorder (2,5,3,6)
I believe the answer is:
at sixes and sevens
'a bigot rolled with rugger match in disorder' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'a bigot rolled with rugger match' is the wordplay.
'bigot' becomes 'sexist' (sexist is a kind of bigot).
'rolled' is a reversal indicator (letters roll back).
'with' becomes 'and'.
'rugger match' becomes 'sevens' (I am not sure about this - if you are sure you should believe this answer much more).
'sexist' back-to-front is 'tsixes'.
'a'+'tsixes'+'and'+'sevens'='AT SIXES AND SEVENS'
Can you help me to learn more?
(Other definitions for at sixes and sevens that I've seen before include "in disarray" , "disorderly - with 33a" , "in a mess" .)
