A disorder specific to young Christian males in which strong instincts to treat females like idealized sisters-in-Christ are perpetually warring with awkward and guiltful sexual longings towards the aforementioned sisters-in-Christ.

When these sexual longings are consummated via even minor sexual affection with an actual sister-in-Christ specimen, the CGS sufferer immediately experiences such guilt that the idealization is destroyed and the sexual attraction is dramatically but temporarily repressed.

CGS manifests itself in myriad ways, including self loathing, purity oaths, increased accountability group attendance, excessive use of the word "stumbled" and unpredictable social behavior wherein the affected individual sends a strong mix of conflicting interest-signals towards any woman to whom he is attracted until she cries, screams or schedules a meeting with her high school youth pastor, who, still recovering from his own CGS, hands her a copy of "I Kissed Dating Goodbye" by Joshua Harris.

A spectrum social disorder that makes a man think he's entitled to date or have sexual relationships with women simply because he sees himself as a "good person."

Level 1: The most mild form of NGS. This from of the disease usually occurs with a man who has been rejected for the first time. Symptoms include: anxiety, depression, irrational fear, lack of necessary social skills, and total obliviousness to how women work. If this man were to try to approach a women, he will come off as a "creep" to this woman, for he will probably use the wrong choice of words. He will also have body language that will make him appear as if he is a "stalker." He is probably just a man who has yet to "come out of his shell."

Level 2: A slightly more severe form of NGS, most common men over 21. Symptoms include: passive aggression, intense frustration, resentment towards women, obliviousness of how the world works, and contemplations of revenge. This man will successfully convince his female victim to become his friend. After the nice guy confesses his feelings, she'll politely reject him. He'll call her out; claiming she only likes to date "douchebags" or "badasses." He'll soon start using derogatory words. The nice guy will return home and start masturbating to silicone-enhanced porn stars. He will google the term "nice guy." He will most likely give the web definitions a "thumbs down," as he is probably a nervous wreck who can't "take a joke."

when a female or females become obsessed with an older male or a group of older males.
typically seen in high school situations when an older guy will talk to a younger girl and despite any amount of ugliness/dickishness the girl will become obsessed and next to ignore or look down on guys of her own age.

A condition where a guy feels he is entitled to dating a girl simply because he has been her friend and let her cry on her shoulder about the jerks. When she is not attracted to him, he choses to blame it on the fact that he has been a "nice guy" and she only wants to date jerks. Really, not the mentality of a guy who is actually nice, because one should not be kind in the hopes of getting a girl and simply be kind for the sake of being kind. Any guy who tries to guilt you into dating him simply because you are friends has the mental affliction known as nice guy syndrome.

When a girl is so physically attracted to a guy that her heart stops for 3.7 seconds, her lungs begin to abruptly function incorrectly, she can't think straight, walk right, stand up, and then she feels like crying because of the face that boy has engraved in her heart (as well as that body my god daddy)

A annoying mental condition in which a heterosexual man concocts over simplified ideas why women aren’t flocking to him in droves. Typically this male will whine and complain about how women never want to date them because he is “too nice” or that he is average in appearance. He often targets a woman who is already in a relationship; misrepresenting his intentions of wanting to be her friend and having the expectation that he is owed more than friendship because he is such a good listener. He is prone to brooding over this and passive aggressive behavior.

He is too stupid to realize the reason women don’t find him attractive is because he feels sorry for himself, he concludes that women like to be treated like shit.

The uncanny ability to miss a target when firing a weapon. Usually applies to any bad guy in any action film ever made.

A nice guy is an informal term for an often young adult male who portrays himself with characteristics such as being gentle, compassionate, sensitive and vulnerable.The term is used both positively and negatively. When used positively, and particularly when used as a preference or description by someone else, it is intended to imply a male who puts the needs of others before his own, avoids confrontations, does favors, gives emotional support, tries to stay out of trouble, and generally acts nicely towards others. In the context of a relationship, it may also refer to traits of honesty, loyalty, romanticism, courtesy, and respect. When used negatively, a nice guy implies a male who is unassertive, does not express his true feelings and, in the context of dating in which the term is often used, dishonestly uses acts of ostensible friendship and basic social etiquette with the unstated aim of progressing to a romantic or sexual relationship.

A guy who goes out of his way to prove his “niceness” to the world but is really just an asshole who cannot handle being told “no” or being rejected in any way shape of form
