ASMR is a tricky feeling to describe, and I can only talk about it secondhand. From what I understand from conversations with ASMRers, it’s a tingle in your brain, a kind of pleasurable headache that can creep down your spine. It’s a shortcut to a blissed-out meditative state that allows you to watch long videos that for someone who doesn’t have ASMR are mind-meltingly dull. Not everyone gets this feeling, and though some people can get the tingles through sheer force of will, most depend on external “triggers” to set them off. Triggers can include getting a massage or a haircut or a manicure, or hearing someone talk in a soothing tone of voice (Bob Ross, the “let’s put a happy tree right here” painter from PBS, is a common trigger), or even just watching someone pay extremely close attention to a task, like assembling a model. It’s not usually sexual—everyone who talked to me about ASMR mentioned that right off the bat—but like sexual turn-ons, different people have different things that set them off: the sound of lips smacking together, a cashier’s fake nails tapping on the register, your friend drawing on your hand with a marker.
