I do, but only just heard about how it's a thing yesterday on This American Life.

This may also be that elusive "fizzing sensation" James May talks about when he drives a really great car...or why I find a old diesel rattle so pleasing.

The term "autonomous sensory meridian response" (ASMR) is a neologism for a claimed biological phenomenon, characterized as a distinct, pleasurable tingling sensation often felt in the head, scalp or peripheral regions of the body in response to various visual, auditory, olfactory, and cognitive stimuli.

Other phrases to describe the sensation refer to it as a "brain orgasm", "brain massage", "head tingle", "brain tingles", "head orgasm", "spine tingle", and "braingasm."
