Stop our peers' recreation? Outrageous! (12)

I believe the answer is:

preposterous

'outrageous' is the definition.
(thesaurus)

'stop our peers' recreation?' is the wordplay.
'recreation?' indicates an anagram (I've seen 'recreation' mean this).
'stop'+'our'+'peers'='stopourpeers'
'stopourpeers' anagrammed gives 'PREPOSTEROUS'.

(Other definitions for preposterous that I've seen before include "Unreasonable - fatuous" , "Utterly absurd" , "Crazy" , "Quite absurd" , "Ludicrous" .)

I've seen this clue in The Telegraph.
