Update November 10: Unsurprisingly, the app turned out to be a hoax and nothing else. Please don’t get into fist fights. The original story is below. 
 
 “Bro, your face is pissing me off, want to throw down?” 
 
 That’s an example of the sort of dialog that goes on in a new app called Rumblr, which can be used to set up fistfights with total strangers — you know, Fight Club style. 
 
 Rumblr is set up like a dating app, except the dates happen in parking lots and back alleys, not restaurants, and they culminate in throw-downs instead of get-downs. 
 
 Here’s the pitch on the website: 
 
 Rumblr is an app for recreational fighters to find, meet, and fight other brawl enthusiasts nearby. 
 
 Lurkers can play too: 
 
 You don’t need to fight to use Rumblr. With Rumblr Explore, anyone can browse and attend fights close by that other Rumblr users have arranged — all for free! 
 
 The app comes complete with a chat tool, and a mapping function to show where fights and fighters are located. You can even filter to show only girl fights or gang fights. 
 
 Actually, the app hasn’t launched on the app stores yet. It could be awaiting approval. The website lets people sign up on a waiting list. 
 
 No sign of any monetization efforts on the site, just an effort to build a large community of punchers. But, you know, Rumblr might be a good site for advertisements from emergency rooms, anger management therapists, or first-aid supplies. 
 
 I hope Rumblr catches on, especially in San Francisco. Sounds like just the thing for all the tech bros around here. ||||| There's a new fighting app called Rumblr that is set to debut Monday at 5 p.m. ET. 
 
 According to the app's Twitter account, users will only be able to access Rumblr through its website and not via a mobile app. The owners claim it's 100-percent real, although the photos and descriptions of the app seem absurd.

 "Rumblr is an app for recreational fighters to find, meet, and fight other brawl enthusiasts nearby," its official website states. "You don’t need to fight to use Rumblr. With Rumblr Explore, anyone can browse and attend fights close by that other Rumblr users have arranged — all for free!" 
 
 The app claims to be "Tinder for fighting," referencing the popular dating app. Basically, users will find a match, schedule a fight and then go after one another. In one of the photos promoting the app, a user messages another user saying, "Bro your face is pissing me off. Wanna throw down?"

 There's been some backlash to the app for obvious reasons. Setting up amateur fights amongst strangers probably isn't the best idea and could lead to some serious trouble. The owners of the app sort of addressed that issue in an interview with FightState.com. 
 
 "What happens when somebody gets killed?" the creator was asked. 
 
 "We’re hands-off after the initial matchup. Hopefully, a funeral," they responded. 
 
 Whether they want to admit it or not, the developers of the app are essentially promoting unsanctioned fights, which a very dangerous proposition. All sanctioned fights must be cleared by state athletic boards, and to circumvent that process by enticing users to engage in unsanctioned fights is potentially dangerous for the sport. 
 
 The Rumblr team also spoke with the New York Daily News and said they aren't in the App Store yet because they have to "hash out legal issues" before Rumblr is approved. 
 
 They also told the Daily News that 78,000 people have already signed up for beta access to the app.
– The Internet is already getting pummeled with Fight Club jokes with the announcement of what may be the strangest app to come along in some time: Rumblr, "an app for recreational fighters to find, meet, and fight other brawl enthusiasts nearby," per its website. The beta version of the app, which bills itself as "Tinder for Fighting," is set to launch Monday at 5pm EST, the app's team told the New York Daily News in an email and via a tweet. The app will supposedly allow users to "get matched with others who want to throw down," scheduling fights between like-minded competitors. It will also post fights on an interactive map by location and type (e.g., girl fights or gang fights, as VentureBeat helpfully notes). Users can set up detailed profiles with their stats—height, weight, wins, losses—and even trash-talk each other using the app's "Chat" feature, per the Daily News. Which sounds intriguing, except that everything about this app screams hoax. The Washington Post lays out the most convincing argument why it's probably just "a marketing stunt, a prank or (best case!) an unsubtle parody," mainly due to the app's "questionable legality" (an assertion backed up by SportingNews.com) and the fact that the app's founders appear to be a "skinny" college junior and recent high school grad who don't seem likely to be the "lifelong recreational fighters" they claim to be. But they insist they're ready to rumble. "We have raised relatively substantial funding from private American investors and the app is fully developed," reads Rumblr's email to the Daily News. The team says the app will be on the App Store after it works out "legal issues," as the paper puts it. FightState.com, going on the premise the app is legit, asked the app's owners what will happen if someone gets killed. The response: "We're hands off after the initial matchup. Hopefully, a funeral." (The App Store took a conservative approach in recently allowing a pot app.)
