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.
