Slang. All of it; the whole thing

I don't go to the beauty spa for just one treatment. I go for the whole enchilada!

Non vado al salone di bellezza per farmi un solo trattamento, ci vado per farmi tutto quanto!

He said the pizza was too big just for the two of us and then he ate the whole shebang

Ha detto che la pizza era troppo grande per noi due soli, e poi se l'è mangiata tutta quanta

My neighbor wants to get rid of all of his furniture. If you want, you can buy the whole shebang for a few bucks

Il mio vicino vuole liberarsi di tutti i suoi mobili e, se vuoi, puoi comperare il tutto per pochi dollari

This problem with this expression is to find out what a shebang is. In November 1869, the Marysville Tribune printed a list of The Idioms of Our New West where it reads that "shebang is applied to any sort of house or office." In June 1872, the Sedalia Daily Democrat printed a piece which used the name just to mean 'thing', and this is the earliest example of 'the whole shebang': "Well, the Democracy can flax [beat up] the whole shebang, and we hope to see our party united." Thus, shebang became simply a colorful way of saying 'thing'
