raver's hangover 

A state of exhaustion the morning after a night out dancing like crazy. Unlike a regular hangover, this is not necessarily brought on by any alcoholic beverage, but by sheer physical exertion.
A typical sufferer will sleep until late in the afternoon, be fairly sore, especially in the feet, and be ravenously hungry upon waking.

Oh, I'm fine, I was just sleeping off my raver's hangover. Let's go get pancakes!

someone else's hangover 

This is when you wake up in the morning feeling like you really tied one on the night before even though you didn't have anything to drink. Through some sort of karmic mixup, you woke up with someone else's hangover, and they woke up feeling like a champ.

me: Ouch. My head's really banging this morning.

you: Well, you didn't have anything to drink last night - must have someone else's hangover.

Wanker's Hangover 

The feeling you sometimes get when you've finished having a wank, in that you feel disgusted with yourself. Similar to PFG (Post-Fap Guilt).

Jacking it to PornHub this morning gave me the worst Wanker's Hangover.

Valentine's Hangover

Valentine's hangover has two definitions.

1. Something bad has happened on Valentine's day, and therefore you are depressed for a period of time afterwards. You have a Valentine's Hangover.

2. Something good has happened on Valentine's Day, so you are ecstatic for a period of time afterwards. You have a Valentine's Hangover.

1. Molly: Why are you so sad?
Daniel: It was Valentine's day yesterday, and my girlfriend dumped me. I have a Valentines's Hangover.

2. Daniel: Why are you so happy?
Molly: It was Valentine's Day yesterday, and my boyfriend proposed to me! I have a Valentine's Hangover.

philosopher's hangover 

The general malaise, fatigue, or otherwise hangover-like symptoms that are caused by discussing or debating a philosophical topic too late at night which resulted in you both (a) cognitively never resolving the issue and (b) losing an entire night's worth of sleep attempting to.

Issa, Ali, and Nick all woke up with a really bad philosopher's hangover after spending all night trying to solve the mind-body problem.

New Year's hangover 

The credit card bill after Christmas buzz. You often go into a rant and be a bitch, not for all people.

When Polly got her credit card bill from December, she had a New Year's hangover for 3 months trying to pay off the bill.

Poseidon’s Hangover 

An afternoon thunderstorm in a college town, usually in Florida.
Named so when a storm pukes up a lot, both violently and loudly.

“Looks like Poseidon’s hangover is about to hit.”
