The act of frolicking around at any waterpark in particular and 'accidentally' manuvering your toe into the crotch of a nearby, and conveniently located fellow park guest. Best performed in a large wavepool or other deeper, agitated water attraction where there is a sizeable group of people in close proximity to one another and limited chance of being immediately discovered as the perpetrator of the act. Usually done in order to satisfy one's urges to make physical contact with a hot, young chick in a way that my wife won't notice.
