Irate man, drunken soak (8)
I believe the answer is:
marinate
'soak' is the definition.
(I've seen this before)
'irate man drunken' is the wordplay.
'drunken' is an anagram indicator.
'irate'+'man'='irateman'
'irateman' is an anagram of 'MARINATE'.
(Other definitions for marinate that I've seen before include "Soak food in flavoured liquid before cooking" , "Soak food in a minaret" , "Pickle" , "Rain team (anag.)" , "Soak meat, fish etc" .)
