deicing the cake

  1. What does she mean by the next sentence?
    Joe’s deicing the cake!
  2. I wonder why Joe has a funny look.


She is using it to mean “removing the icing from” (“icing” in this case is a kind of sugary decoration).

The “joke” is that “de-icing” normally means removing the ice from (e.g. from a car windscreen, runway, etc.).
