Hold on... it depends on what you mean by 'intellectual' and what values said 'cool crowd' have.
For example, going back to the Jersey Shore example then you need to like what they like and come off like them. Same with any other group. If someone from the 'cool crowd' tries to hang out with some nerds the nerds are going to reject them. They're too unalike and from different worlds.
So it's not necessarily about dumbing yourself down. It's about appealing to the group you want to be a part of. If that group loves anime then at least enjoying anime is kind of a requirement. If the group you want to join can't go a weekend outside of the stripclub then you're probably going to need to hit up a stripclub with them.
Or maybe your idea of a cool crowd are art intellectuals who enjoy going to art exhibits and drinking fine wine at a vinyard.

So forget about dumbing yourself down, you don't have to. Hector is a great example of this, especially if you've read his King of College book. It's clear that Hector likes philosophy and would (if I recall correctly, someone correct me if I'm wrong as it's been a while since I've read any of his stuff) regularly start talking about philosophy sometimes. Yet he was also a popular guy in a frat.
Does that sound like a combination you would assume right off the bat? Philosophy and frat?
___
So again, it's not about dumbing yourself down, it's about enjoying what that group enjoys. Or at least be willing to talk about it.
Here's an example, I was a well-liked and respected guy within some heavily religious groups. I am not religious and even told them that God and I had a bit of a falling out in my childhood. But I still participated in that sub-culture, I still regularly joined in conversations about things they were talking about and brought what I wanted to say within that context.
Pain was a discussion once that I was able to talk about quite easily, as an example. Another was people and psychology.
You can be who you want to be and even talk about some of the things that you're passionate about. You just have to remember:
1) it has to be something you're passionate about and you have to bring that energy out so that other people can feel it
2) you have to already be somewhat known in the crowd
3) DON'T OVERDO IT --> very easy to do
4) do your best to bring everything back to whatever they're already talking about or interested in (once you get the hang of doing this it's quite easy, just look for things that what you want to talk about have in common with what they're talking about)
___
So I guess what I'm trying to say is this: people like people who are like themselves. Birds of a feather flock together. If you can bring out aspects of yourself that match the group you want to join (or cultivate those likes/interests) then you'll naturally be able to float into those groups.
And one other thing, don't try to stereotype the group you want to join or dismiss them as beneath you. That slight dismissal is going to shine through and you will get rejected if people pick up on it. People, naturally, don't like to be rejected.
As an example: God and I do not get along. But I never once thought of any of the religious people as beneath me and I even tried to understand them a bit better. I even came to somewhat envy their faith because I've seen the turnarounds it can make in someone's life.
Right on. Should I also hide the lame things about me? Such as the fact that I haven't had sex in a couple years? I'm afraid it also might mean social death.
Also, should I pretend to like the same things they like? It might be tricky. For example, I really don't want to lie and say that I drink, because then they'll ask me to drink with them.
What else should I talk to these 100 IQ folks about? My guess is that I should make jokes, tell anecdotes, hmm that's about it.
You should always strive to put your best foot forward. It's not about hiding aspects of yourself, it's just about bringing out the best of yourself.
Here's an example; never have I ever been rejected for talking about my Yu-Gi-Oh card collection with women. Literally not once. But then again I don't go around talking about my cards with every chick I see. Personally I call it my 'dork collection' and women actually think it's awesome. Because by the time I show them that part of me they're already hooked and now they're just getting to see more of me.
Make sense?
As for not having sex in a couple of years it depends on how you frame it, first off. Second off, it's not really anyone's business and most people don't care past high school. If it does get brought up you can be honest as long as you're not ashamed by it.
In fact, if it does get brought up (not by you because then it will look tryhard) you'll look extra strong if people try to shame you for it and you just brush it off.
"What!? You here this, this poor schmuck hasn't had sex in years! Lmao"
"Not sure why that's funny... but okay there guy." --> make sure to say it through a mixture of genuine confusion and like you're talking down to them.
As for liking what they like, that's non-negotiable. Don't pretend. If you don't actually like it then you have to be curious about it. If you pretend then people are going to reject you because you're the outsider at that point.
You don't have to lie about not drinking. Other than when I was like... maybe 13 or so, I've never been made fun off for not drinking. Or at least nothing comes to mind. It's gotten brought up a shit ton for sure, but I just answer it matter of factly because it's not something to be ashamed of. I don't like the taste and therefore I don't drink.
I don't look down on anyone that drinks or anything like that. That's just how it is.

Lastly about your comment on the 100IQ folks. You talk about whatever they enjoy talking about. Not every person with a certain IQ is going to like the same thing.
Just like not everyone with a genius IQ is going to like the same thing. I've talked to actual geniuses and they're just like everybody else, they have their likes and their dislikes. An exgf was one of these people who came from a family of extreme music lovers. Everybody played an instrument.
Then there are other people who are into physics. Some are into psychology, some are into chess, some are into this and others into that.
At the end of the day though, people are people. We like what we like.
My suggestion is forget about the 'cool crowd' because I can already tell that you kind of look down on them. They're going to reject you because if I can pick it up through text then they're going to pick it up in person.
Instead of focusing on the cool crowd, focus on a crowd that will bring you women that you'll have some common interests in with the group itself (or if you're like me, develop a passion for people instead and approach them with that mindset). For example, some chicks want to climb the corporate ladder, and some of them are hot. Some of them are ugly.
Some chicks are passionate about photography and modeling, some of them are really hot and some of them are ugly.
Then there are gym chicks, sports chicks, so on and so on. Just figure out what you're interested in that hot chicks are interested in and focus on that group. Not only will you enjoy being around those kinds of people more (aside from sex) but you'll enjoy your life more. And you'll be able to be closer to the real you.
Though the 'real you' isn't actually what you think it is anyways. But that's a whole other discussion.
