Grifter's ploy
I believe the answer is:
scam
'grifter's ploy' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for scam that I've seen before include "Fraud, trick (slang)" , "Dodgy business" , "A slangy swindle or fraud" , "Swindle, fraud (colloq.)" , "Rip off" .)
