The Old Fashioned Fuck, also known as the "O.F.F.", is a simple missionary position fuck between a man and a women, just like they used to do in the olden times. Also, is known to be the nicest way one can fuck a girl, and the most gentleman-like.

Todd: Oh LAWL, I thought we were going to have a problem.
