The NEET man is the epitome of male dominance and masculinity
Let's start by looking at his body pillow. His body pillow is large. Her domineering size makes her presence known without him even needing to point himself out. She is kawaii desu, as a result of her high levels of moe. This gives her the appearance of youth and arousal. He is then covered by his comfort blanket. This comfort blanket skin reminds us of his true vulnerability, a feature that developed due to being exposed to the repetitive circlejerk of social life, made to ignore such a petty condition. It also has a psychological effect on the observer. The comfort blanket reminds us of our past, deep fears that emerge from our primal subconscious.
The NEET man's demeanor is one of alphaness. He is introspective, rational, and can be explosively sexual. His behaviour strikes confusion into the more foolish, bestial races of man (n*rmiefag dogs)
The summit of expression of his masculinity on his body is his penis. The NEET man's penis is largest of all the social castes. As the penis is the penultimate symbol of manhood, this alone would suffice to make the NEET man the most masculine of men. This large penis is able fulfill the desire of the neediest of women, being able to more than fill all the recesses of the vagina. Its length ensures that when it ejaculates, the potent NEET seed will immediately enter the womb of the woman the NEET man impregnates.
In total, the NEET man expresses this masculinity in a most exemplary manner in bed. When he fucks, he unleashes the entirety of his lusts and desires upon his partner without any restraint.
All this is the reason why the NEET man is the epitome of humankind.
