The act of taking a shit on the side of the highway when there is no bathroom availible.
Gary had a serious case of turtle head poking while traveling down I-696 near Detroit. With no shitters in sight, he pulled over and took a Highway Dump in front of his car. He used his pants and underwear to wipe his ass, and was on his way.
