Whenever a male is sexually aroused during the night and wants to masturbate but is too lazy or scared that he will wake his parents up when he moves to get tissues. He then masturbates with the intention of not nutting but ends up losing control and overestimating his choad causing him to nut all over himself. This putts him in a much worse situation than before by forcing him to get up and clean it and also risk being caught by his parents with the task of explaining why he has nut all over himself. Basically, a literal fucking nightmare come true.
"Dude, did you hear about what happened to Andrew and why he's not at school today? I heard that he had The Nocturnal Nut of Nightmares and his mom caught him bro!"
