Gamorreans, derogatorily known as «pigs,» were a sentient species of green-skinned pig-like humanoids that hailed from the Outer Rim planet of Gamorr. They grouped themselves in clans, each of which was led by a warlord and a Clan Matron. A number of Gamorreans were employed by the crime lord Jabba the Hutt to act as guards throughout his career.

Gamorreans had a clan-based society. Each clan was ruled by a female leader, the Clan Matron, and a male leader, the Warlord. Although the sows farmed and hunted while the boars waged wars, the Gamorrean society was in fact a matriarchy. Indeed, a Warlord held his position by way of marriage to a Matron rather than force, although Matrons did make their selections based on the boars’ combat skills. Gamorreans saw war as glorious, and violent clashes between clans were rife.

Because of their low intelligence, Gamorreans tended to be both stubborn and loyal; philosophically, they believed that any problem could be solved by hitting it with brute force. They had a language of their own that sounded like mere grunts and squeals to outsiders. Although they could understand other languages, such as Galactic Basic Standard, they found most of them too difficult to pronounce. Gamorreans respected those who used swears in the Gamorrean language, loving to use insults against others and their families. Their love of vulgarity meant they were not always annoyed when they were referred to as «pigs.

Technologically speaking, the Gamorreans were primitive, and they favored melee weapons like vibro-axes, vibro-lances, and Gamorrean battle-axes over blasters. They never discovered space travel on their own. Moreover, Gamorrean boars failed to maintain personal hygiene, rarely changing their clothes or wiping the streaming mucus from under their snouts. Gamorreans chopped down areas of their natural forest habitat to make room for farming.
