Jamaican sect member (5)
I believe the answer is:
rasta
'jamaican sect member' 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 "Bob Marley, for one" , "Jamaican cultist" , "One following religion" , "Member of religious movement originating in Jamaica" , "Member of cult worshipping Haile Selassie" .)
