This is when you wake up the morning after you've done something awful/humiliating whilst intoxicated and suddenly remember your previous night's activities.
Oh my God, I didn't feel too bad this morning when I woke up, till I realised I'd called my best friend a whore, snogged my boss's significant other and mooned the woman who was my teacher when I was six! I was SO under the guilt quilt!
