Some eargasms may affect your whole body in an inevitable way. For instance, Tequila's
Salta ("
Jump", see translation
here). The song is from 1981, but if it had been released in the "Internet age" the whole world would be jumping with it. I've heard it hundreds of times, but even now, if I listen to it on my ipod when I walk the streets, I can't help moving my body.
