A form of preversion. Involves inviting a group of foot fetishistists to a house in which shoes must be removed to gain entry. They'll all come assuming that they can sneak away at some point to have an illicit sniff of the shoes left by the door. However, what actually happens is you steal the shoes while they are in the other room and take them away for a horrible sniffing.
"Shoes?!? Where are the goddamn shoes?"
"You after the shoes too?"
"I was after the shoes, was everybody after the shoes?"
"Fuck! It's a funky trap!"
