A sexual act in which (having taken a laxative and eaten lots of corn for lunch) one defecates in their partner's mouth.
Troy: "I heard you and Shirley hooked up last night."
Pierce: "Yeah, she's a freak. She gave me a Nebraskan Nightmare. Best lay in years."

Unexpected dissapointment. When an expected positive outcome turns out to be exceptionally negative. Refers to an awful sour tasting beer much like salad dressing, disguised as something delicious. It costs $36 a bottle, and tastes like $2 vinegar.
Last night was a real Blueberry Nightmare ....
When I finally got her pants off it was a real blueberry nightmare down there...

A dream that does not illicit fear but an extremely uncomfortable feeling. Similar to that feeling of being in a crowded room of loud boisterous foreigners asking for directions and not knowing the language or able to find the exit.
(From my husband whom is not a pilot woke up and said...)
"I don't want to fly planes anymore, I've been flying them all day this is such an awkward nightmare" (...before falling back to sleep)

A mutation of the dystopian nightmare where society is devolving rapidly in a desperate and dangerous death spiral while hordes of soulless unkillable monsters roam the land reaping, raping, screeching and taking everything you have before feasting on your brains which are in short supply in this apocalyptic future world.
I had the craziest Trumptopian Nightmare last night where I was a mighty and regal bald eagle soaring high and proud above America until I was shot in the back and plunged into a murky swamp where I was devoured by alligators and a zombie turtle.

When one has a sex dream about someone, something, or some situation that they would never want to be involved with sexually
Greg had a sex nightmare about Kelsey last night. She rufied him while they were playing beer pong in the dream.
Jenn had a sex nightmare that she was fucking a horse last night after watching 40 Year Old Virgin.
Foard was giving it to me in the living room at my family reunion in my sex nightmare last night. Nothing worse than grandma and grandpa watching from the couch.
