max-ditz
To assume the most simple, brainless, ditzy attitude and manner possible in order to gain a real OR psychological advantage in some social, commercial or legal interaction.
Lovely lawyer Llyshelle needed to get the vexatious, soon-to-be-ex wife to open up how she married JUST for his vast wealth, so she went max-ditz with a high blonde wig, trampy clothing and makeup to lull the wife into thinking she was a loser of a lawyer. Llyshelle had her screaming her life-sucking wedding plans within 5 minutes.
