Actually, in restaurant lingo, the term "86" means kill it as in "Kill the order". It has expanded over the years to phrases "86 that project" as in "kill the project".

With that in mind, consider the name of the french-made abortion pill RU-486. Now, say that with the voice inflection of a question. Coincidence? R U 4 86?

Doesn’t 86’d also mean forcibly removed?

“The bouncer 86’d him from the bar.”
