It's pretty tough to keep up with all the new social media apps cropping up these days. There's Snapchat, Tinder, Vine, and now Yik Yak, a relatively new, location-based app.
Yik Yak hosts anonymous social chat rooms where up to 500 nearby users (or "Yakkers") can connect through GPS tracking.
But the app is also causing some trouble. Some users have used the app for cyber-bullying, others have posted bomb threats, and classes at Mira Costa High School in Manhattan Beach, CA were cancelled yesterday and today after some vague threats were posted through the app.
Social media expert Niki Weber joins Take Two to explain more about Yik Yak.
