Frotteurism

I dont think Im alone when I say this has happened to me. I didnt realize there was a psychological term for this until today...
Even though the word makes me giggle the disorder is quite sad.

Frotteurism: Men have a paraphilia called Frotteurism when the focus of their sexual urges are related to the touching or rubbing of their body against a non-consenting, unfamiliar woman. Usually the male rubs his genital area against the female. Most commonly, the man chooses to attack in a crowded public location and then he disappears into the throng of people. Frotteurism usually begins in adolescence and the abnormal behavior tends to decrease when the man reaches his late twenties.
