I am occasionally (aka often) wrong, so I asked Claude what it thought about 86'ing. Below is what it had to say. I thought the history was of interest.
The prompt:
I think the term 86 is generic for getting rid of someone, e.g. firing. Others are claiming that it's shorthand for killing. What do you think?
Its response:
You're right, and the "killing" crowd is largely wrong or at least working from a very minority usage. Here's what the evidence actually shows:
The primary, well-established meaning is exactly what you said: to get rid of, remove, or refuse service to someone or something. Merriam-Webster defines it as "to refuse to serve a customer" or "to get rid of or throw out" someone or something.
The origins are murky, but they clearly point toward removal/rejection, not violence. The term first appeared in the early 1930s as soda-fountain slang meaning an item was sold out. By the 1950s it became a verb, initially meaning "to refuse to serve a customer," and later broadening to "to get rid of; to throw out."
As for the "kill" meaning, it's real but very much secondary and recent. The verb sense of "kill, murder, or execute" only appears in documented usage from 1978 decades after the term was already well established. Merriam-Webster acknowledges some equate it with "to kill," but notes this usage is infrequent, stating: "We do not enter this sense, due to its relative recency and sparseness of use."
