todorrow

Specifically, a word used when you're certain if you say "Tomorrow" someone will say "Surely you mean later today?", and if you say "Later today" someone will say "but I'm about to go to bed, it's 5:45am ffs!"

"Look, it's getting light, it's too late for this - let's get some sleep and discuss it todorrow"

or, if it's *really* late; it can be used as
"It's so late, it's practically todorrow" - which of course is impossible, by definition
