Dogknapping 

Whenever you touch the tips of your toes on the bottom of another’s nutsack lightly

Like: Why did you just touch the bottom of my nutsack lightly

Haden: It’s called dogknapping

dogflapping 

The act of pleasuring two men at the same time, without either of them knowing about the other. Simply put, the woman kneels within a large dogflap (like a catflap in a door, only larger), and men 'take' her from either end, without being able to see each other.

I was out in Oxford last week, and saw STFCBird dogflapping two tramps in Argos, near Bonn Square.

Dicknapping 

1. When a woman knowingly lies with a man who is beholden to another, with specific intent of actualizing divorce once both parties are caught in the act.
2. The act of separating a man from his penis so as to hold it for ransom.

Wife to adulteress, upon catching said party engaging her spouse mid-coitus: "Ain't gon' be no motherfucking dicknapping up in this motherfucker. Please believe."

"Damn girl, I see Lorena Bobbit, but I woulda dicknapped that backwoods motherfucker for all he was worth."
