Rude, boorish (3-8)
I believe the answer is:
ill-mannered
I believe this is a double definition.
'rude' is the first definition.
(I know that rude can be written as ill-mannered)
'boorish' is the second definition.
(I've seen this before)
(Other definitions for ill-mannered that I've seen before include "Rude - uncouth" , "Rude, discourteous" , "Boorish - uncivil" .)
