Snobbish, arrogant (5-2)
I believe the answer is:
stuck-up
I believe this is a double definition.
'snobbish' is the first definition.
(I've seen this in another clue)
'arrogant' is the second definition.
(thesaurus)
(Other definitions for stuck-up that I've seen before include "Hoity-toity" , "Overly conceited or arrogant" , "Toffee-nosed" , "Snobbish, proud" , "Snooty" .)
