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.
