Incest Jar

An Incest Jar is a jar filled with family to family, generation to generation sperm, which is a big jar, usually carried with a rope, tied to a truck for transportation. It’s usually used for a torture method against family members apart of the cult named, “Peppa pig’s affairs”

Jane got put into the incest jar, therefore she’s in the “Peppa Pig’s Affairs cult”.

diet incest

Being an adopted child of no blood relation to one's adopted parents, the act of having sex with a relative. It has all the flavor of incest without the incest, technically since there is no close biological link between the two (or more) individuals partaking in the act.

Mike: Hey, Nick, did you hear Brian fucked his older sister?

Nick: Awww, gross, dude!? What the fuck?

Mike: I know, but technically they're not related. Brian is adopted; so, it was diet incest.
