Restaurant lingo meaning "take an item off the menu." By extension it can also mean to get rid of almost anything (including doing away with somebody). The Urbandictionary entry attributing the term to the 1980s is erroneous. I worked as a short order cook in the late 1960s and it was in use in a half dozen NewYork city joints where I worked. Oldtimers say the term was around in the 1940s and that the derivation is Article 86 of the New York Liquor Code which describes the circumstances under which liquor should be withheld from a customer.

to eighty-six a pregnancy is to medically terminate it, taken from the name of the "abortion drug" RU-486.

A woman might eighty-six a fetus in the earliest weeks of being pregnant, with the help of a health care provider who can administer a brief series of oral dosages.

Eighty-sixing is normally done only up until a point when a pregnancy is so far along that a surgical procedure is needed in order to abort.

Eric: Yo, Kevin. You're lucky Jenny eight-six'd it after your fling at the lake last summer. Otherwise you would've been stuck paying child support.
