ramrod

Device used with muzzleloaders to push the projectile up against the propellant.

Ranch or trail foreman, usually the first or second person in charge. The person responsible for getting the work done.

An erect penis.

Half a second after that, she had him totally pinned while he thrust at her crotch with his ramrod, going thud thud thud like a blind dog in a maze. Hitting everything but the entrance she craved.

To force.

That new project manager is just the one to ramrod this through to completion.
