Originated by Mike, of the Chicago land area, the sexual act of placing your wang in between the ass crack of one woman and then having a second woman rub her vagina (or beef curtains in this case) on the top. Direct reference to the popular Chicago sandwich, the combo, which combine Italian Sausage and Italian Beef.
Not wanting anyone to be left out, Zack initiated the comboner to make sure Kelly and Lisa were both satisfied.
