Complaint gets hipster in trouble (9)
I believe the answer is:
nephritis
'complaint' is the definition.
(nephritis is a kind of disease)
'hipster in trouble' is the wordplay.
'trouble' is an anagram indicator.
'hipster'+'in'='hipsterin'
'hipsterin' is an anagram of 'NEPHRITIS'.
'gets' is the link.
(Other definitions for nephritis that I've seen before include "Inflammation of the kidneys" , "kidney complaint" .)
