Disgusting position (4)
I believe the answer is:
rank
This clue is a double definition.
'disgusting' is the first definition.
(thesaurus)
'position' is the second definition.
(I know that rank is a type of position)
(Other definitions for rank that I've seen before include "Grade; foul" , "Downright" , "Grade; flagrant" , "Row - grade" , "Highly disagreeable" .)
