Can anyone think of similarly generation-defining food items in media?

Even though it didn’t come out until the later part of the 2000s, the Portal cake is probably the official cake of that decade.
Better yet, it’s based on a real black forest cake from a bakery near Valve

Would that mean that the cake is not, in fact, a lie?

Or is it a deeper commentary on the realism of a representation of a thing, a la Magritte’s The Treachery of Images? The cake is a lie because it’s not a cake, it’s a representation of a cake.

Doc, this is heavy.

There’s that word again, “heavy”. Is there something wrong with gravity in Portal?
