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.
