I get this quite a lot, though not always in the same body area. "Shiver" is the best word I've found to describe it.

It's definitely triggered by emotional and spiritual things. I can also evoke the sensation again by meditating and thinking of it... it doesn't seem to be any more complex than a wave of some type of energy. Of course, sometimes, the simplest things are the hardest ones to truly understand, and the most rewarding once they are understood. ^^
