A purging of tension in the middle ear canal that feels extraordinarily acute, a bit itchy and orgasmically pleasurable.
Putting on my headphones, my middle ear canals ajusted pressure to receive the sounds, giving me an eargasmic sensation as the canals fluttered with sharppleasure.
Originally used to describe the intense sensory rush achieved by wearing earplugs up to a week before a concert, then removing them just prior to The Band (who cares about openers anyway?)
It's been rough at work trying to hear with these earplugs, but the bass kick will give me one helluva eargasm.
