Shocking; monstrous (10)

I believe the answer is:
outrageous
I believe this clue is a double definition.
'shocking' is the first definition.
(I've seen this before)
'monstrous' is the second definition.
(thesaurus)
(Other definitions for outrageous that I've seen before include "Exorbitant" , "Shocking" , "undignified" .)
