86'd
In the early days of the Remington and Royal typewriters, when
paper was expensive and the results messy, overtyping to block out errors (e.g.: old prices on the daily menu or items out of stock) was common. Repeated typing
of the the digits
86 over a word would cover almost any previously typed word. The X was also used, and when you either typed "X" or "
86" over a word the resulting edit was always called an "
86" and anything so blotted out was "
86'd". That's the connection with Delmonico's, and other downtown NYC eateries where the menus were printed for the
day or week and had to be "overtyped" to eliminate items off the menu.
