Overyesterday

The day immediately preceding yesterday; two days ago. A modern, efficient alternative to the phrase "the day before yesterday," constructed logically to mirror the word "overmorrow" (the day after tomorrow).
A word used because saying "the day before yesterday" takes too much time and effort.

"I haven't seen him since overyesterday."
"Wait, was that Monday?"
"No, today is Thursday, so overyesterday was Tuesday."
