The principal of my small-town high school heard kids talking about pump jack parties. He thought we were going out to a pump jack to get drunk and ride the pump jacks. Apparently, in his day, that's what kids did. He brought in a guest speaker from a local oilfield company to talk to the senior students about the dangers of doing that.
We were dumbfounded by the talk because none of us had ever thought to ride a pump jack. What we called a pump jack party was just when a specific couple parked their car in the country to have sex.
Older people in the community have since confirmed that riding pump jacks was indeed a thing.
My Mom once said to me, "Be good, but if you can't be good, be careful."
