the act of having an erect penis, or cock and running full tilt into a womens vagina, or pussy. if you swing the other way it can be done the same way, but in to anus, or bum hole.
When nailing a chick, banging her so hard that when you thrust you end up slamming her head clear through the headboard. IF done correctly and with enough force, you might just be able to crack the dry wall of your shitty apartment.
