When a female wakes up with an erect, hard, throbbing clitoris, often after having an erotic dream; female equivalent of a male having morning wood.

Dude where have you been all morning?
Man, I was all fucked up last night, I woke up and had to drop the Morning After Shit. It was seriously like a one footer. I feel so much better.

A swollen, chaffed or sore asshole that can only be achieved after a solid ass-pounding friday and saturday night. Most common in insecure drunk women, dope fiends, inmates and Justin Beiber fans.
Austin awoke that morning to find his asshole swollen and practically rubbed raw from all his guido buddies after a spectacular weekend of fist pumping and partying on the Shore, a textbook case of the sunday morning asshole.

When you sneak a morning after pill in a milkshake for some chick you busted a nut in. Banana is the best flavor.
John: good morning babe, I made you a delicious banana milkshake. (morning after milkshake)
Susie: oh thanks nigga, fuck me harder.

The condition one may have when they have been retaining their fecal material (intentionally or not) longer than the body would prefer, causing upset stomach, headache, and nausea, not unlike that of morning sickness with a human baby, except the symptoms will immediately go away with a good poo session. Now you're just pregnant with a poo baby.
Tyler: Oh, God! My stomach! I feel sick!
Kyle: Do you need to shit? Have you gone this morning?
Tyer: No I haven't. What's that got to do with anything?
Kyle: Man, you got morning shit-sickness! Go take your morning dump and you'll be good to go!
