Wholesome, gentle, auditory-pleasing sounds meant to calm an individual, put them to sleep, or physically experience an amazing sensation called "tingles" throughout your body. Emphasis on wholesome,
BTW.
It has been said that Bob Ross was the first to do ASMR, albeit unintentionally. Then, in the late 00s, ASMR videos finally started taking off on
YouTube. These were mainly just simple whispering videos. It was around 2013-14 that
people really started experimenting with sounds of various objects and substances (referred to as 'triggers'), whatever made a good sound when you
tapped or scratched on it.
