For fictional people past puberty, any wild party with all genders, teen or otherwise, is all about one thing: getting it on. This can be a good or bad thing, depending on many factors. Although one absolute in fiction is that if it's a teenage girl going, and you're her guardian, it's always a bad thing.
If it's planned and advertised as an orgy, it doesn't count.
- Played for Laughs in Kaguya-sama: Love Is War where Miko's overactive imagination and repressed libido ends up leading to the following conversation with Tsubame when the latter invites Ishigami over for a Christmas party.

Tsubame: What?! Oh no! You have things all wrong! I was going to invite you too, Iino-san!
Miko: A threesome?!
Tsubame: No!! I'm inviting people over because I'm throwing a party!
Miko: An orgy...?!

- The page quote comes from PCU, but the film actually inverts the trope: The Pit's house band decides to name themselves "Everybody Gets Laid," so that they can capitalize on people coming in thinking an orgy is going to happen.

- In Smokin' Aces, Buddy Israel's penthouse apartment is obviously showing signs that the party held the night before the action of the movie starts was one of these.

- Inevitably riffed on in MST3k; during a screening of Laserblast. The protagonist is at a birthday party looking through the house for his girlfriend. To be fair to the trope, he has already wandered past one couple who were making out. He opens a door and pokes his head in:
Tom Servo: Hey, there's a dozen naked teenage girls in there! That's what happens at these teen parties - it's true!

Bob is intrigued (but without Midge to "trade," he can't participate either).
- Bob Seger's "Horizontal Bop" tells about someone trying to get one of these started:
Somebody bring the records
Somebody bring the brew
Someone get a house

Someone tell the ladies
Someone make a deal
If we can't find a house
Then someone find a field
Grass is good as carpet
Anyplace is fine
It's time to get rockin'
Babe it's time to shine
Tell 'em we'll be dancin'
Dancin' til we drop
It's time to get down and do the horizontal bop

- The clip for Charlie Puth's "Marvin Gaye" is one of these. It starts with a boring prom party until the music makes everyone start making out and banging on the spot.

Benson: ...it's not that kind of party, Muscle Man.
Muscle Man: Oh... nobody turn on the lights.
