Ever heard the expression "feature creep"? It's when the director of a project keeps comming back to you and saying, "Well, what if we added THIS feature?" when you're getting close to the deadline and you really don't have time to add another feature. Well, this is its spoonerism brother, creature feep!
Yes, the feeping creature. It looks cute and soft and fluffy, with the big green Puss-in-Boots eyes, but just you wait until it gets those pointy little teeth in your project. You'll think cute and fluffy, all right!
