When you think you woke up feeling shitty due to the fact that you ate too much cake and got too little sleep the night before, but find out later that you actually have the stomach flu.

The aftermath of a night rich with hate and anger. The night may have involved the telling off of, or arguments with, one's closest friends, excessively passionate texts, or the open broadcasting of one's own depression to people who could really care less. Such bursts of hate are not drug- or alcohol-fueled but rather driven spontaneously by a mix of deep-seated grudges the brains own chemicals and hormones which, once they have resided, leave the person with nothing in the morning but regret and humiliation.
*Wake up, open phone, flip through texts* Ohhhh fuckkkk did I really call her a slut and talk shit about her boyfriend and say she should've been with me for the past 2 years instead? SHIT! I'm gonna see her at work in like an hour! What the fuck was I thinking? Baaad hate hangover.

A cross between exhaustion and euphoria, usually lasting for about a half hour, that one experiences after taking a huge shit.
Guy 1: I just dropped a HUGE load and now I've got a wicked poo hangover.
Guy 2: Dude, the best thing for that is to sit down and take it easy for a few minutes.
