Noisy reveller (8)
I believe the answer is:
carouser
'noisy reveller' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for carouser that I've seen before include "boozer" , "merrymaker" , "He's having a wild time on the town" , "Noisy reveller" , "He's out on a spree" .)
