With great power comes great responsibility. 

If you've got a friend you want to prank, some asshole who won't stop including you in group messages, or a lot of free time on your hands, we've got you covered. Thanks to the good people of the internet, you can crash your unsuspecting victim's phone without the inconvenience of driving to their house and turning it off yourself. 

Copy and paste this little monster:

effective.

لُلُصّبُلُلصّبُررً ॣ ॣh ॣ ॣ

And send it to whoever didn't send you a Christmas present last year. 

Twitter, filled with more assholes than ever, is amused. 

All we want to know: who the hell came up with this? We like to imagine armies of internet trolls trying every conceivable combination of text and images until something works. Because that is the true nature of the internet: annoying people relentlessly.
