Imagine a set of fingernails being slowly dragged across the cover of a leather-bound book. Or the heavy crinkling of thick pages of newspaper. If the thought alone causes a pleasant feeling to roll down your spine, enveloping you, you’re probably experiencing an Autonomous Sensory Meridian Response, otherwise known as a “brain orgasm.”

Though not a true orgasm and still unsubstantiated from a scientific point of view, ASMR has amassed a sizable following on sites like YouTube and Reddit, whose ASMR communities produce and share videos as if it were closely guarded intel — a network of pleasure-seekers who’ve swapped their baseball cards for prolonged cases of the tingles, and swear on their lives that a 45-minute video of a woman brushing her hair is worth it.

Back in November, Medical Daily explained what happens in the brain during ASMR, but we never gave you a taste of the stuff. Do you find yourself moved by the punctuated, yet gentle, sound of someone’s voice? What about a hair brush being run through a patch of knotty locks? Maybe you’re satisfied with the humble click click of a typewriter. Have a listen, and see what tickles your fancy.
