This Slate article on ASMR videos is fascinating.
The video I have just described is called “~♥~ Let me take care of you ~♥~,” and it has well over 50,000 views on YouTube. It is what is known as an ASMR role-play. ASMR stands for Autonomous Sensory Meridian Response, which refers to a particular combination of pleasurable physical and psychological affects experienced by a surprisingly large number of people when they hear things like soft whispering, quiet tapping, and gentle crinkling noises. If you search for “ASMR” on YouTube, you will find countless videos like this one.
