Trolls exist for one reason, and one reason only: to annoy the crap out of people because they have nothing better to do. One such troll with an Xbox One decided to piss a couple of fellow gamers off by trolling them using the video game console's voice command feature. It's pretty ingenious and he really didn't have to do much.
All he had to do was set his username to 'Xbox Sign Out' and the gamers (and the console's voice command feature) did the rest. Enjoy!
