It looks like "Grand Theft Auto" isn't just for nerdy 12-year-old boys or immature – and single – grown men, as this writer likes to believe. Grannies are really into "GTA 5" too.

On Tuesday, YouTube user Gamergran87 uploaded a video entitled “British Gas Rampage” showing a white-haired elderly woman wearing large headphones in a small inset video playing "Grand Theft Auto 5," the new version of the popular video game that just came out online last month. The cursing grandma on a digital killing spree has been viewed more than 1 million times since Tuesday.

It seems the potty-mouthed granny was using the game to blow off steam. The uploader of the video, presumably the elderly woman featured in the split screen, said her "GTA 5" rampage was a response to gas-price hikes in Britain.

“Sorry about the language, everyone, but I got a letter from British Gas and I had to let my anger out!” she wrote. “20% price hike?! You thieving bastards. Have some of this.”

However, as The Mirror pointed out, it is unclear whether or not the grandma is really playing or if she is narrating for someone else playing. But whoever is dictating the game, the player goes on a rampage punching pedestrians, setting people on fire and blowing up a gas rig from a helicopter, all while a sweet old lady curses with a British accent.

"Hello, what do you do for a living? Work for British Gas, do ya? W----r," she says at one point. "You want central heating? I'll give you central heating,” and proceeds to light a man on fire.
