hey i thought of a decent gimmick to use to take wallets that does involve physical misderection but it doesnt have to be ne where near the butt.

take a strip of metal abou one inch in width and about a foot and a half long, and bend it around a card case so that it makes a hook about the width of an average sized wallet.

heres what you do: walk behind the victim and "accidetnally" bump into him and using the heel of your hand thrust it firmly into the bottom of there sternum now when i say firmly i dont mean hit them because it is a pressure point nad it can cause stomach problems if hit with hard pressure. and at this exact same time us the gimmick and put it into there pocket with the hook side down. and the long solid side on the out side of the pocket and pull it toward you gently. this will cause the hook to go around the wallet and the pocket to open up creating a ramp for you to pull out the wallet.

I'm not sure if that is a new gimmick but i think it is pretty effective.

Front pocket is the easier.
