Nick just a little bit (5)
I believe the answer is:
pinch
This clue is a triple definition!
'nick' is the first definition.
(both can mean steal)
'just' acts as a link.
'a little' is the second definition.
(I've seen this before)
'bit' is the third definition.
(thesaurus)
(Other definitions for pinch that I've seen before include "amount of salt?" , "Steal (colloq.); one felt by the poor" , "appropriate" , "Economise - steal" , "Pilfer" .)
