Apparently, this real life video was taken on the subway in Edmonton, when a woman choked out a man on the subway. While that's strange enough, she also growled and acted possessed as she accosted the man. Clearly, a video of this nature is making the rounds on the internet. While it's scary, it's also strangely intriguing. The absolute craziness of the human condition in mind blowing. This girl has to be either crazy or on drugs. You won't believe how this video ends!

Watch out for strong language. I can assure you, if this happened in front of me, I'd be cursing like a sailor, too.

Here's additional video captured of the girl before the incident:
