Wikipedia describes the autonomous sensory meridian response (ASMR) as "an experience characterized by a static-like or tingling sensation on the skin that typically begins on the scalp and moves down the back of the neck and upper spine." Videos which endeavor to trigger that response have become quite popular over the past year or so, with most videos featuring "anonymous women delivering soft-spoken voice-over narration" according to the New York Times. That's not the case here.
While most ASMR videos utilize weird, often unidentifiable sounds, NatGeo's take on the craze looks to nature for inspiration, featuring a wide cast of Yellowstone's animals and soundscapes. Regardless of whether or not the sound of ram horns smacking together in super-slow-motion triggers your ASMR, it's still incredible footage from TGR's backyard.
