What is the origin of the idiom "everything but the kitchen sink" and when to use it?

The idiom "everything but the kitchen sink" likely originated in the United States in the early 20th century. It humorously suggests that everything conceivable has been included, except for the literal kitchen sink, which is too large or impractical to include in a particular situation. This idiomatic phrase is used to describe a situation where a large or excessive number of items or elements are included, often to the point of excess.
