Stole pig, removing the last (3)
I believe the answer is:
boa
'stole' is the definition.
(both can mean a type of scarf)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for boa that I've seen before include "Large snake provides a neck decoration" , "Large reptile" , "Python" , "strangler" , "One who puts the squeeze on" .)
