On Jan 1st 2021, humans will no longer require sleep, and now have a need for a 4th meal of the day. What do we name the new meal?

It already has a name (at least in French) and that is medianoche (don’t know why we used the Spanish word for midnight though).

Midrats. Abbreviated for midnight rations.
