A type of cup stack in beer pong where the only 3 cups remaining are the front cup and the 2 back corner cups, creating 3 separate islands. This type of stack can be called during the one allowable restack by a player or team that is feeling extra confident and would like to show off, but can also occur naturally. If this stack occurs on its own by a player or team that has hit the 3 cups that are not a part of the Philadelphia Cheese Grater, it is referred to as a "Natural Philadelphia Cheese Grater." When a Natural Philadelphia Cheese Grater occurs the the team shooting at the stack can no longer use their restack for the remainder of the game.
When a dude doesn't wash his privates for at least a week or 2 even through working and such and starts to accumulate "cheese" under the skin and a girl goes down on him with a can of hotdog chili.
A dude at the bar asked me if I wanted to come back to his place for a chili cheese dog and winked at me.
