Big Willie Style is a shock-style sex move. It is accomplished by first having regular intercourse between a girl and a
guy, but right as the guy is about to
cum, he pulls out, plunges it into the girl's ass, and unleashes his load while singing "Na na na na na na na - gettin jiggy wid it," the classic hit by Will
Smith. A greater effect is added if the guy raises the roof while doing this.
