Tricky situation for man's cow in trouble (3,2,5)
I believe the answer is:
can of worms
'tricky situation' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'for man's cow in trouble' is the wordplay.
'in trouble' indicates an anagram.
'for'+'mans'+'cow'='formanscow'
'formanscow' is an anagram of 'CAN OF WORMS'.
Can you help me to learn more?
(Other definitions for can of worms that I've seen before include "What may prove problematic" , "Bird's convenience food" , "Something likely to prove awkward" , "Complex problem" , "nasty problem" .)
