Lout disrupted funfair (7)

I believe the answer is:

ruffian

'lout' is the definition.
(I've seen this before)

'disrupted funfair' is the wordplay.
'disrupted' indicates anagramming the letters.
'funfair' is an anagram of 'RUFFIAN'.

(Other definitions for ruffian that I've seen before include "Lout" , "Aggressive, rude troublemaker" , "Roughneck" , "Scoundrel" , "Hooligan" .)

I've seen this clue in The Everyman puzzle in The Observer.
