To walk with short steps, swaying the body from one side to the other, like a duck or very fat person; to move clumsily and totteringly along; to toddle; to stumble; as, a child waddles when he begins to walk; a goose waddles.
Another method of marking cattle. A waddle is formed by cutting a piece of skin so that it will grow into a distinctive hanging mark in a certain location. Used in conjunction with brands and earmarks. The example shows a neck waddle. Waddles and dewlaps often are more visible than brands in cold weather country where the winter hair obscures the brand, and are useful for quick recognition and sorting.
