The Gooey Greenback is a simple manuever, requiring only yourself, some ho, and a single dollar bill. Before you are about to nut on/in the girl, (acheive this any way that you like), take aim at her forehead. After nutting all over her face, then grab the one dollar bill and slap it on to her forehead. If done properly, the bill will stick on and stay there. This is the most degrading sexual act you can perform without the use of feces.
I gave that bitch her money back, in the form of a gooey greenback.
