Two men sit in the driver's seat of two parked trucks, and their respective female companions sit in the passenger's seat. The trucks are parked facing the opposite direction so that the driver's side windows align. While the two men receive oral sex from the women in the passenger seat, they reach their left arms out the window and high-five while simultaneously exclaiming, "Daaaaamn!"
When Jordan finally bought his new truck, he and his best friend took their girlfriends behind the hardware store and parked next to the dumpsters, where they all participated in a Hoover Dam.

A dam in Boulder City, Nevada, built as a Federal project by order of then USA President Herbert Hoover. It dams up the Colorado River, and thus created Lake Mead, the largest man-made lake in the world. It is used for water supply, recreation, and hydro-electric power.
Originally called "Boulder Dam", it was later named "Hoover Dam" after former USA President Herbert Hoover.
