Dreadlocks wearer, for short (5)
I believe the answer is:
rasta
'dreadlocks wearer for short' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rasta that I've seen before include "Member of WI religion" , "Member of religious movement originating in Jamaica" , "Member of a religious movement with Jamaican origins" , "black believer" , "Disciple" .)
