A complete fourth meal eaten with friends after a night of drinking, usually at a 24-hour diner between the hours of 2 and 5 AM. Shamefast is a great opportunity to recap what may have been missed (or forgotten) earlier that night.
Dood, I'm over this. Let's head out and grab shamefast at the diner on the corner.
