A dog having ears which flop over themselves. To flop these ears back and forth is called "flooping". A single flop is a "floop". Thus, if a dog has ears which may be flooped, it is a flooper.
Awww, your Chow-Chow is adorable! Such a cute little flooper! May I floop him?

An attempt at any kind of cooking that goes horribly wrong
For instance, you have committed a flooper when you frost the cake before it is cool and the top layer slides off the bottom layer and lands on the counter; or when you accidentally use salt in place of sugar in a recipe; or when you horribly, grotesquely burn the roast.
