Sweetener giving defensive player stimulation at first (8)
I believe the answer is:
kickback
But I can't explain it at all! Could you help me understand?
(Other definitions for kickback that I've seen before include "Bribe - recoil" , "Bribe paid by seller to purchasing agent" , "Commercial bribe paid by a seller to a purchaser as an inducement to buy" , "special gift" , "Recoil; illicit payment" .)
