Casual Sex on Facebook. It's a thing.

ThinkStockThree unidentified California college buddies have developed a Facebook app called Bang With Friends to connect people who want to have sex with each other. Here's how it works: People anonymously select those on their friend list who they'd like to sleep with, then the app notifies the two people if they've selected each other. The app only launched last week but it's already racked up over 20,000 users and facilitated 1,000 hookups, according to The Daily Beast.

The goal is to take the rejection out of asking a totally random person on your friend list for sex (because a request like that is always a tad awkward) and to "cut to the chase" (because who has time to date anymore?)

“[Sex] should be something you’re expressive about, that you’re comfortable with, and if there’s a beautiful woman or a handsome man that you’re interested in, you shouldn’t hold back,” said one of the app’s creators. “We’re just giving you closer access to knowing the truth."

"By being honest and forward, we’re taking the no bullshit approach [to sex]," said another creator.

The guys threw the site together in two hours after a Red Bull-vodka fueled discussion about the downsides of online dating sites. “What a lot of people want is just to skip all the shit and get to the sex" explained one founder. And business is apparently booming because when you visit the company page, they're now calling for job applicants.

But is Bang With Friends a method women would even use to have casual sex? One look at the app's "How It Works" section suggests no. After clicking past an image of a half-naked girl lying on a bed with her dress thrown over her face, users are given instructions against the backdrop of penis illustrations. Sexy, huh?

We asked a few women if Bang With Friends would appeal to them. "It's too transactional," one said. "If I'm in the mood for meaningless sex, I can go to a bar, flirt with a cute guy, and have my drinks paid for first."

"There's nothing about this app that would make me want to have anything even remotely resembling sex," said another.

While another said simply, "Um, no."

If that's not problematic enough, get this: Even though the founders promise that they've updated the app to prevent being matched with say, your dad, when presented with a list of F Buddies, how would the app know who you're related to if you're not tagged as relatives on Facebook? Plus, Buzzfeed points out that before you even download the app, you can see which friends of yours are using it. Nothing embarrassing about that! Especially if your boss is on your friend list.

We rate this a sex fail!
