“And Shagga son of Dolf.” That was the first voice, deep and deadly. A boulder shifted to their left, and stood, and became a man. Massive and slow and strong he seemed, dressed all in skins, with a club in his right hand and an axe in his left. He smashed them together as he lumbered closer.
...
“Little boyman,” Shagga roared, “will you mock my axe after I chop off your manhood and feed it to the goats?”
...
Shagga glowered, a fearsome sight to see. “Shagga son of Dolf likes this not. Shagga will go with the boyman, and if the boyman lies, Shagga will chop off his manhood-”
“-and feed it to the goats, yes,” Tyrion said wearily. “Shagga, I give you my word as a Lannister, I will return.”
...
Boys emerged hesitantly from the stables to see to their horses. Shagga did not want to give his up. “The lad won’t steal your mare,” Tyrion assured him. “He only wants to give her some oats and water and brush out her coat.” Shagga’s coat could have used a good brushing too, but it would have been less than tactful to mention it. “You have my word, the horse will not be harmed.”
Glaring, Shagga let go his grip on the reins. “This is the horse of Shagga son of Dolf,” he roared at the stableboy.
“If he doesn’t give her back, chop off his manhood and feed it to the goats,” Tyrion promised. “Provided you can find some.”
...
The door behind him opened with a crash, so violently that Tyrion almost dropped his cheese. Ser Kevan leapt up swearing as the captain of the guard went flying across the room to smash against the hearth. As he tumbled down into the cold ashes, his lion helm askew, Shagga snapped the man’s sword in two over a knee thick as a tree trunk, threw down the pieces, and lumbered into the common room. He was preceded by his stench, riper than the cheese and overpowering in the closed space. “Little redcape,” he snarled, “when next you bare steel on Shagga son of Dolf, I will chop off your manhood and roast it in the fire.”
“What, no goats?” Tyrion said, taking a bite of cheese.
...
“This is Conn son of Coratt. Shagga son of Dolf is the one who looks like Casterly Rock with hair. They are Stone Crows."
...
Tyrion saw Shagga catch a spearman full in the chest as the fool came on at a run, saw his axe shear through mail and leather and muscle and lungs. The man was dead on his feet, the axehead lodged in his breast, yet Shagga rode on, cleaving a shield in two with his left-hand battle-axe while the corpse was bouncing and stumbling bonelessly along on his right. Finally the dead man slid off. Shagga smashed the two axes together and roared.
...
When they were alone, Lord Tywin glanced at Tyrion. “Your savages might relish a bit of rapine. Tell them they may ride with Vargo Hoat and plunder as they like—goods, stock, women, they may take what they want and burn the rest.”
“Telling Shagga and Timett how to pillage is like telling a rooster how to crow,” Tyrion commented, “but I should prefer to keep them with me.” Uncouth and unruly they might be.
