A phenomenon amongst particularly sadistic runners. When it comes to time leave a party and the runner is too intoxicated to drive, he/she has their friends drop them off at their house so they can run to their car in the morning. Can represent a distance from 1 mile to 26.2.
Ben: Man, can you drive me home? I'm way too wasted to drive.
Mike: How are you going to get your car man?
Ben: I'll need to exercise off this hangover anyway, I'll just go for the morning after marathon.

The nasty, sweaty, slimy and stinking mess that is your crime scene after a particularly heavy night. Usually the state of them will offend even yourself, and you are often in such an extremely hungover state that you have missed your opportunity to shower that day. The only cure is to scrub thoroughly and treat with Gold Bond. This can have various causes such as: 1)dancing all night, allowing for a sufficient coating of sweat to turn rancid while you sleep; or 2) after a night of particularly excessive sexual exploits, the 'maturing' of 'love fluids' on the affected area.
Today is probably one of the worst days of my life, I've got a beastly hangover, don't have any of the right books for my lectures, and a killer case of morning after balls. Can I borrow your shower?

The morning-after pancake is served to your partner after you've had intercourse and you're not sure if you wore a condom or if she was on the pill. It is essentially a morning-after pill mixed into the pancake batter.
Hey, I fucked Kelsey last night and I don't remember wearing a condom so I made her some morning-after pancakes.

Flat shoes that can roll up and fit easily into a purse so that a girl won't have to do the walk of shame in her heels from the night before.
Thank god I brought my morning after flats to the party last night, otherwise I would have had to walk home from that rando's house in stilettos the next morning.

n.) The underwear your girlfriend found in your dresser that she decided to put on. (May be described as absolutely sexy.)
My girlfriend took a shower and turned my boxers into "morning after" panties because she couldn't find her thong.
