Halfway between a hard on and a totally flaccid penis. Interestingly, the semi-on is becoming rarer and rarer in today's society, eclipsed as it is by the boner and the laredo. The semi-on's natural habitat is middle school and high school locker rooms, where it is created by young boys in an effort to demonstrate their virility. Intriguingly it is often understood as a sign of faggotry, resulting in a beat down for the perpetrator rather than the expected admiration.

Other times the semi-on can occur include:

* When the individual is too drunk to support a full erection,
* When the individual is somewhat aroused but controlling the feelings and suppressing the erection,
* When the individual is interrupted during sexual activity (or thoughts) but was turned on enough that the erection did not immediately disappear.

Occasionally the word is used as a pejorative to describe individuals who are somewhere between being flaccid cocks and total dicks.
Jimmy masturbated a bit before showering with the other boys: he wanted to look his best in front of everyone. He proudly entered the shower flaunting his semi-on. Later that night, surgeons were unfortunately unable to completely reattach Jimmy's left testicle, as its trip through the sewage system had left it in a rather poor condition.

Davan's grandmother surprised him nude: he tried to hide his excitement, but ended up with a semi-on.

After thirteen beers, John was only able to manage a rather pitiful semi-on, even as the dancer gyrated her hips in his lap.

That moderator is such a Semi On: he never takes a stance on anything, but still comes off as a total dick.

Though Derek was shocked by the interruption of the entrance of Laura's, his semi-on quite handily demonstrated his continued interest in sexual activity.

It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.
Given the nature of the word, it is more appropriate to design cases where the interaction is made with a moving object, for example, a ball.
Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.

Nerd neck 

A "human" that spends so much time playing video games that their posture is level nerd neck. Everytime anyone goes tryhard they hunch down and their neck gets longer there fore a nerd neck is always hunched down cause they're always going try hard. In other words a nerd neck is a try hard, since their neck is 100% longer than the average human being due to playing too many video games and taking them serious, nerd necks are not even considered human anymore but something more sad. Nerd necks are often found on fortnite, their natural habitat usually being tilted towers.
