The act of sexual congress, usually with respect to an encounter of a casual nature. The term "frapsteak" is believed to make reference to Dr. Emilius J. Frap, renown Diesel Fitter from Bratislava, Slovakia. The penis is the "frapsteak" and the boogie is, well, the boogie.
I was doing the frapsteak boogie with this nasty chick at our house.
