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.
Jenny: I just came up positive on this
pregnancy test. It was just a one night stand. I'm gonna eighty-six it.
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.
