Addicts keeping sober, with flipping rowdy encouragement (7)
I believe the answer is:
attaboy
'addicts keeping sober' is the definition.
I can't tell whether this defines the answer.
'flipping rowdy encouragement' is the wordplay.
'flipping' says the letters should be written in reverse.
'rowdy' becomes 'yob' (synonyms).
'encouragement' becomes 'atta' (I can't justify this - if you can you should believe this answer much more).
'yob'+'atta'='yobatta'
'yobatta' back-to-front is 'ATTABOY'.
'with' is the link.
Can you help me to learn more?
(Other definitions for attaboy that I've seen before include "word of encouragement" , "Expression of encouragement, Tay boat (anag.)" , "Come on!" , "What's said to encourage" .)
