Camp and role-playing horseman (9)
I believe the answer is:
caballero
'horseman' is the definition.
(I've seen this before)
'camp and role-playing' is the wordplay.
'camp' becomes 'cabal' (cabal is a kind of camp).
'and' is a charade indicator (letters next to each other).
'playing' indicates anagramming the letters.
'role' is an anagram of 'lero'.
'cabal'+'lero'='CABALLERO'
(Other definitions for caballero that I've seen before include "Spaniard politely" , "Spanish gentleman" , "Bear local away for Spanish cavalier" , "Horseman" , "Foreign gentleman" .)
