I got it once in high school 10th grade blue balls not blue tooth. I'll never forget it, it was awful. The next weekend before the same tease came over and we got to second base (or maybe to the shortsop) and no further for hours. But I had a plan, I jumped up and said "Oh sh!t that pizza is hitting me!" and ran to the bathroom. Backpressure was immense, I told my buddies about the geyser later on. The girl got the nickname "Old Faithful" because of that episode.

I don't know if she ever found out why.
