Look at king hugging drunken dean (6)
I believe the answer is:
gander
'look at' is the definition.
(I've seen this before)
'king hugging drunken dean' is the wordplay.
'king' becomes 'gr' (short for Georgius Rex, King George in Latin).
'hugging' is an insertion indicator (outside letters hug or embrace inside letters).
'drunken' indicates an anagram.
'dean' anagrammed gives 'ande'.
'gr' placed around 'ande' is 'GANDER'.
(Other definitions for gander that I've seen before include "Glimpse" , "Male bird - look" , "Butchers - goose" , "Male goose; look (colloq.)" , "Male goose - quick look" .)
