In cricket, a ball bowled low along the ground; also historically, a military weapon or vehicle designed to destroy obstacles at ground level.
Compound: 'daisy' (suggesting something low, close to the ground) plus 'cutter' (something that cuts), implying a trajectory that clips at the height of daisies.
Cricket players use 'daisycutter' to describe a delivery that skids along the grass—it's called that because it would literally mow down daisies if they were in its path!
