"Party in the back" hairstyle (6)
I believe the answer is:
mullet
'party in the back hairstyle' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mullet that I've seen before include "Starfish" , "Fish - bad haircut" , "Fish (red or grey)" , "Fish's name for a hairstyle" , "Fish, male hairstyle" .)
