half-nut 

a person who is a bit slow and dim witted, due to the fact that only half of the sperm (aka. "nut") that reached the egg, made it through the wall of the embreo...leaving the fetus (and forthcoming person) lacking in some basic skills and cognitive understanding of anything

Dude : "Does that guy realize he's hitting on his boss's wife or does he just not care?"

Other Dude : "He wouldn't know either way. The poor guy is a half-nut from some inbred trailer-town in some forgotten county"

Half Nut November 

A branch of the infamous No Nut November challenge, but now the person can decide whether to refrain from masturbating either for the first 15 days of November or for the last 15 days of november.

Half Nut November can serve as a good "trial" period before attempting the full on No Nut November challenge the following year. This will give them the relevant experience and will give them motivation (providing successful completion of Half Nut November).

Person 1 : "Are you participating in No Nut November?"

Person 2 : "I don't want to dive into the deep end straight away so I think I might try Half Nut November this year and then No Nut November the following year."
Person 1 : "Oh alright, Baby steps man. You have my respect."

Half Nut 

Men who are below 6ft, are conceived from pre cum or when a woman spills out half of the semen from her vagaina which results in the baby being born from half of the initial load and in turn the growth of the child is affected, which results in them being small in size.

Martyn is below 6ft in height, he was conceived from half of a load, possibly pre cum or just a cheeky half nut, due to this error in conception he has grown up to become a BMW driver.
