The act of defecating on a woman's chest, spelling "donner" with your shit, then titty fucking her. When you reach your climax, ejaculate in a the shape of an L on top of the shit.
Dude I heard Tim gave Will a dirty larkin last night! I totally saw that "cumming".
The Dirty Eugene is a deviant act perpetuated by the loneliest of sorts, the nerds of this world so obsessed with video game fantasies that they creep into other aspects of their lives. Eugene was selected as the human name that best represents this type of person.
Assuming that such a human can get laid, the act is as follows:
While banging a girl doggy style, the guy grabs his favourite gaming controller (generally the the "flight stick" style of joystick) and shoves it in her ass. This is customarily followed by a proclamation of "New High Score!"
Nerd 1: "Did you hear about john Doe?"
Nerd 2: "No, what happened?"
Nerd 1: "He got beaten down by Jane Doe after giving her the Dirty Eugene"
Nerd 2: "At least he's got the new High Score..."
A dirty Adolf is after anal sex, you insert your finger into the rectum and smear the material under the female's nose, just like Adolf Hitler's mustache. See dirty sanchez
