The unfortunate result after a delicious ice cream cake has melted too much to retain it's shape. The cake is moved to the sink and continues to be eaten with a spoon. Often occurs after people are too drunk to remember to put the cake someplace cold.
Dude 1: That cake was delicious! Got any more?

Dude 2: It's in the sink. It was melting all over the counter. Here's a spoon. Have some more.

Dude 1: Hmmmm, sink cake is awesome =
