Ever hear someone say, "yeah, throw in the whole kit and kaboodle"?
What does it mean?
Kit, in this sense, means a circular wooden vessel, made of hooped staves. I guess you could say a kit is like a basket.
A kaboodle is any large collection of things or people.
So "kit and kaboodle" is basically a lot of things or people packed tightly in an enclosed space. Like a packed elevator. Or subway. But it could also be a basket of candy or a bouquet of flowers.
The phrase's vague meaning should render it out of date.
But people still use it. Kind of like gumshoe.
