bock down
buckle down and make a serious effort. "bock" from the German, Bock, a mountain goat; by inflection, the devil, darker side, or wildness. My maternals used to ask us children whether they should drive the bock out of us. "Soll ich dir mal den Bock raustreiben?" From this it could be affirmed that we were onto some significant disturbance.
"Bock down and do some business, boy!"
