The feeling you get after a night of drinking or partying, as you remember something horrifyingly embarrassing you've done the night before. This feeling may sink in as you go through your text message or call history, or hit you midday at work as you remember your bad decisions. You silently hate yourself. It's a sunburn, but of shame.
