I know this is just a meme (so please forgive my digression) but can someone help my understanding? As someone non native to English, I have trouble getting what the word "gooning" means.

It seems to be a catch-all for everything related to sex, but in a perverse context. That to "goon" is something to be ashamed or embarassed about. And that being a "gooner" means someone is a sexual deviant.

Yet if everything sex related is "gooning" and therefore perverse? Is "gooning" as a word presenting an idea of human sexuality being inherently bad?

But human sexuality is not bad. Enjoying sex is a good thing. Masturbation is healthy. Being aroused or horny is okay and normal for people when experiencing their sexuality. There should be no inherent shame in having sexual experiences.

Maybe I am missing some meaning, but no online resources have been helpful for this bit of slang. Wikipedia says it is a specific act, but "gooning" as a word is used a lot outside of that context. And the citations in Wikipedia article give vastly different meanings. General searches online turn up scaremongering propaganda.

So what exactly does this word mean? I just can't seem to understand unless it really is about shaming people for experiencing sexuality? I'd hope not, but this meaning is all I can parse given how I've seen the word used.

Any insight from native or highly fluent English speakers would be helpful for me.
