taking an entire stick of butter, sticking it into a womens vagina and having normal sex with it in there until it gets soft from the sweat. then you take it and put it in the womens anus, have anal sex so it gets mixed with her feces then let her poop it out into your mouth, thus creating a buttery poopy nugget.
