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.
