Skinflints (6)
I believe the answer is:
misers
'skinflints' is the definition.
('miser' can be a synonym of 'skinflint')
This is the entire clue.
(Other definitions for misers that I've seen before include "Mean people like Scrooge" , "They're stingy hoarders" , "They hoard money" , "Penny-pinchers like Scrooge" , "Persons with short arms and deep pockets" .)
