Bizarre request - go out (9)
I believe the answer is:
grotesque
'bizarre' is the definition.
(I've seen this before)
'request go out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'request'+'go'='requestgo'
'requestgo' anagrammed gives 'GROTESQUE'.
(Other definitions for grotesque that I've seen before include "Outlandish" , "Fantastically hideous" , "Comically ugly" , "Freakish" , "Horribly distorted" .)
