pig killer

A social pariah or outcast, one living on the edge of society, or otherwise shunned by the majority.

Source: Mad Max III: Beyond Thunderdome. Pig Killer is the name of one the characters who has literally killed a pig for food.

In the dystopian, energy-hungry world of Mad Max, in a place known as Bartertown, pigs are used to produce methane gas which provides electricity. It is therefore a criminal offence to kill a pig, and anyone found doing so has the words "Pigkiller" branded or scratched into their chest, and they are treated as a social pariah from that point on.

A norwegian mongoloid. His mouth is a deformity, so you just have to play along whenever he says something. Don't let his name fool you, he may call himself a beast, but he's smaller than a minature pig. He doesn't identify as a furry, but he's basically a pigkin.

Sadly, he's not Bionic Pig. Bionic Pig is way more popular.
