Share everything outrageous about blokes (9)
I believe the answer is:
allotment
'share' is the definition.
(allotment is a kind of share)
'everything outrageous about blokes' is the wordplay.
'everything' becomes 'all' (all things).
'outrageous' becomes 'ott' (short for over the top).
'about' is an insertion indicator.
'blokes' becomes 'men' (bloke can informally mean a man).
'ott' enclosing 'men' is 'otment'.
'all'+'otment'='ALLOTMENT'
(Other definitions for allotment that I've seen before include "Vegetable plot" , "Plot for cultivation" , "Distribution of shares" , "Portion, distribution" , "cultivated area" .)
