trimorrow 

The day after tomorrow.

Today = Day 1
Tomorrow = Day 2 (as in, Two-Morrow)
Trimorrow = Day 3 (as in, Tri-Morrow)

If it's Saturday and you're talking to a friend who doesn't realize the Dallas Cowboy game is the Monday Night Football game instead of a regular Sunday game, you might say to him, "Dude, the Cowboy game is trimorrow, not tomorrow."

"Never put off today what you can do trimorrow."

until tomorrow 

A one day trend that originated from the era of the Coronavirus pandemic of 2020, specifically on March 24, wherein people's boredom led them to do nothing better than to log into instagram and spend the whole day doing challenges. It's basically a challenge where you have to post an embarrassing picture of yourself and delete it the next day.
