In the books
In the Song of Ice and Fire novels, Shagga, son of Dolf, is a member of the Stone Crows, one of the mountain clans. He is a strong, large man who prefers to wield two weapons in combat. His favoured taunt is to threaten to remove someone's manhood and feed it to 'the goats' (even when there are no goats in the vicinity). He is not the most intelligent of men, but is extremely dangerous in battle.
