Also, it was the closing line in M*A*S*H years before it was uttered by Darth Vader: P.A. Announcer: (clears his throat) Attention. Tonight's movie has been "M*A*S*H." Follow the zany antics of our combat surgeons as they cut and stitch their way along the front lines, operating as bombs and bullets burst around them; snatching laughs and love between amputaions and penicillin.

Radar: No, sir. That's the one he came in.
Colonel Blake: Oh, very good. Come along, my dear.

When not used in a poker game context, "all in" means that one thing is completely inside something else. No more of said object will be able to enter after this point. Often used in sexual situations.

Originally and still a poker metatphor, 'all in' has also come to mean a situation whose subject is unreservedly involved, without qualification. Fully committed. In this sense the term "all in" is almost the same as its denotative opposite, "all out," as in all-out warfare.

All in means you don't stop for Sundays.

All in means nobody can talk you out of it.

(from New York Times online, October 17, 2011):

Mr. Immelt’s remarks took on the tone of a halftime pep talk. He said that with a clearer regulatory structure, an increased export base and an “all-in” business climate, the United States would be able to compete on a global front.

---Note that the Times used the term 'all in' with a hyphen separating the two words, which is customary when such a term is used as a single adjective. (Compare: "Frank is just flat-out broke".) Also note that the Times put slightly distancing quotation marks around the phrase in the above Immelt citation. This probably means that the Times writer recognized the phrase as a colloquialism, not yet fully acceptable standard written English, in this extended (non-poker) usage. Some grammarians (cf. Strunk and White, THE ELEMENTS OF STYLE), object to ironic or distancing quotation marks on the theory that if a term or phrase is known to most readers, introduction or contexting is not necessary. Most likely, though, the New York Times' elaborate style sheet does not forbid such use.
