Kit and caboodle
The full expression is the whole kit and caboodle, which means the whole lot and it is first attested from America during the mid-19th century. The euphonic kit is often omitted, as in the whole caboodle, or sometimes spelt kaboodle. It has a connection with the word boodle, which is also American but dates from much earlier, during the 1600s, and means a large quantity, especially money with the connotation of graft or illegal money. American etymological sources maintain the origin is from the Dutch boedel, meaning property, inheritance, or possessions. If true, then it does fit succinctly with the whole kit and caboodle, meaning the totality of one’s possessions.
