 It's fun. It's a goof, and it becomes your in-house or family word because the kid said it wrong or somebody misunderstood or it's just ridiculous. In my house, my wife likes to say aminals instead of animals because it's a common metathesis, the transposition of the sounds. I say fambly because that is, for some people, a dialect pronunciation of the word family, and I just like the way it sounds. Like chimbley.
