"Gooning" may be most simply defined as that state usually achieved after a prolonged edging session, when a man becomes completely hypnotized by the feeling radiating his penis. Since a gooning state can only be achieved after edging, the man's dick will have become mightily aroused at this point and every caress the male genitals are subjected to will trigger potent elation. As the man keeps edging and thus keeps experiencing intense pleasure, he enters a state of trance where his mind intimately merges with his cock : the gooning state, where he and his dick become one. To be even more accurate, when the gooning state is achieved, the man's body becomes for all intents and purposes an appendage to his erection. When this state is achieved, the male becomes freed of all social codes of conduct, and his arousal, alone, dictates his reactions. As a result, a gooned out man will become very expressive and demonstrative : he may become very vocal, while his body and face might take on undignified expressions and poses, all in response to the intensely exquisite caresses his penis is exposed to. Hence the term "goon", since at this point the man effectively looks like a silly, foolish, or eccentric person.

Gooning is not a narcissistic manifestation. Narcissism is extreme selfishness, with a grandiose view of one's own talents. Rather, gooning is closer to a meditation experience, where the mind and the body align, focused on a single thought (or feeling, in this case).
I spent 10 hours gooning over the weekend.

For males: the act of becoming completely self-absorbed with your penis and masturbation, such that your face and mannerisms takes on the personality of a goon: tongue out, vacant expression, grunting, muttering. Men gooning often prefer hours of edging/erection to actual release/orgasm. An artifact of modern times and plentiful porn.
After smoking a huge bowl, Andy looked forward to the hours of gooning that followed.

The act of a very addicted or chronic masturbator; getting so into masturbating, or jacking off, that the dude becomes a total goon; becomes stupid on his own cock. Can think of nothing else but busting a nut.
Big Bro: Dude, I'm sorry. I didn't know you were jacking off.

Lil Bro: I'm not JUST jacking off bro, I'm fucking gooning on this dick!

A goon king. One similar to the king of kings but has added goon-like powers. A goon who out performs all others in life no matter how awkward or foolish he/she may behave.
Seth: Whoa! Who is this goon? I've never seen him before.

Brent: I don’t know, but he has the ability to swing any lady, solve any logical problem, feed any starving family, and bring peace to any society while acting like a jackass at the same time.

Seth: ... such a king. How do I describe someone this uber?

Brent: The goon of goons.
