Unruliest are shot - not hard playing this? (7,8)
I believe the answer is:
russian roulette
'this?' is the definition.
The definition suggests a singular noun which matches the answer.
'unruliest are shot not hard playing' is the wordplay.
'not' suggests deleting specific letters.
'hard' becomes 'h' (abbreviation used in pencil classifications).
'playing' is an anagram indicator.
'unruliest'+'are'+'shot'='unruliestareshot'
'unruliestareshot' with 'h' taken out is 'unruliestaresot'.
'unruliestaresot' with letters rearranged gives 'RUSSIAN ROULETTE'.
Can you help me to learn more?
(Other definitions for russian roulette that I've seen before include "chancy business" , "highrisk game" , "risky business" , "Deadly gamble" , "suicidal undertaking" .)
