Preevning 

A part of day time between afternoon and evening. Made up by Sheldon Cooper in Big Bang Theory.

Howard: Your date is tomorrow afternoon 4:30.
Sheldon Cooper: That's not afternoon. That's preevning

What?

It's a time of day I invented. It better defines
the ambiguous period between afternoon and evening:
preevning.
