When a guy makes a Tony's Pizza and puts the hot pizza on the girls back as she's bent over and being fucked in the ass. A "wild slim" can only be successfully completed if the whole pizza is eaten before you bust your load. Also, this sex move can only be done with a Tony's Pizza, but topping choice is optional.
I heard she got 3rd degree burns from the wild slim her boyfriend gave her.
