Just to be practical for the sake of if anon is genuinely asking a question, see here
>>29078632This anon basically explained it perfectly.
Slampigs are a sexual object rather than a person. Its like if you were searching for porn categories, but this concept of a fat piggish woman who just wants her holes to be slammed and used, its a fetish, from both sides.
Using "hotwife" porn category as a similar example. Its wives with a fetish (and often hubands fetish, so involves cuckoldry too) who want to get fucked by random men, or in gangbangs, in thressomes etc, want to service men for pleasure, and be used by them for pleasure. Often including their husband or while the husband watches. A fetish.
So same with slampigs but they are generally not married women past a certain age doing a kink with their partner. Though slampigs dont really have an age category. I supposed even 50+ yo women could still be, or still want to be a slam pig.
