The act of engaging in any behavior or committing any act of stupidity that only a jackass could do.
Speeding on icy roads "because your car or truck CAN" and swerving in and out of lanes around other cautious drivers. Like, the jackassery of the SUV driver on icy roads during a blizzard led to him/her losing control and flying off the bridge to a horrible death in icy waters.
