piledriver
Drives posts down
A piledriver is a machine that hammers heavy posts (piles) into the ground to create foundations for buildings, bridges, and docks.
The term extends to anything delivering powerful downward force—a piledriver punch, a piledriver wrestling move where an opponent is driven headfirst into the mat.
He hit him with a piledriver of a right hook.
