I think a whimsical type name can have a sort of purpose. Sometimes a name goes from being descriptive to being prescriptive. It feels like a straightjacket, preventing you from adding code that would otherwise naturally fit there. In that case I think a whimsical name can be a good idea. Then later when the dust has settled, when you reach the top of the mountain and get a clear view of things, then you can revisit the name.
