I don't know. Pop culture does reflect societal norms and values so I would say that in some cases it would be an indication of what a society considers ok.
Careful examination of the pop culture, its role, audience and reactions could probably tell you a few things about a society. Flipping through a list of comedy tropes, however, doesn't.
Not the least because most comedy works by incongruity and resolution, which is to say, SOMETHING there must be different from the normal. Situations which play out exactly as would be normal and expected IRL are invariably not funny.
And especially for genres like dark humour or gallows humour, the thing that makes it funny IS that it's something horrible, It doesn't mean we take it to be ok. The fact that it's about something horrible is what makes gallows humour work.
Also not the least because, if you've read the list of tropes, you've probably noticed that:
A) it includes mutually exclusive stuff, and
B) a trope being
subverted in a movie also counts as the same trope.
But generally, things that work in movies don't work that way IRL. For example, in the context of this thread, the most obvious example is the
Rape Is Love trope, which nevertheless doesn't mean that any society in history actually took that to be a generally acceptable way to declare one's love. It's something that only really works in fantasy-land.
But do you know of any instance where a woman is raped for comedic effect?
Are you kidding? There is a whole rape joke genre. E.g., (and may the mods have mercy on my soul for it

, but, hey, you asked)
Two nuns are taking a shortcut through the woods and are jumped on by some bandits who start raping them. "Forgive them Lord, for they know not what they do," says one nun.
"Nah, " says the other, "mine does."
Or,
"Yesterday I saved a lady from a rape..."
"Oh, that's wonderful of you! How did you do that?"
"Well, I just persuaded her."
And a few more, but, hey, I should cut it out, I'm probably coming across as a bigger a-hole than on goatse already
Then there's web-comics. Just off the top of my head, I can think of at least three strips about rape on Sexy Losers, including a tentacle rape episode, and one parody of a cooking show that was actually about how to get a girl laid by getting her "marinated", i.e., drunk to the point of being barely conscious. Or on the somewhat less funny side, there's this:

Again, I better stop and leave it at two examples.
Or from movies, while it did get toned down lately because of feminists getting offended (*melodramatically shakes a fist at the feminists*

), we have such examples as Revenge Of The Nerds where it's apparently zany hilarity to pretend to be someone else while wearing a Helloween mask to score sex with someone who thinks you're someone else.
ETA: plus, if you're taking your information about culture from TV Tropes, shouldn't you also notice the
Rape Is Ok When It's Female On Female trope too? And especially if you look over the other side of the globe to Japan, there's a whole genre of using, yes, rape of a female as comedy material or as hot sexy stuff, especially by another female.
