Dugu Qiubai, literally "The Loner Who Seeks Defeat", is a fictional character who is mentioned by name in three wuxia novels by Jin Yong (Louis Cha). Nicknamed "Sword Devil" (劍魔) to reflect his prowess in and devotion to the practice of swordplay, he attains the philosophical level of "swordsmanship without a sword", which means that he uses swordplay techniques in combat without the physical existence of a sword.
Dugu's surname "Dugu" (獨孤) is made up of two Chinese characters that literally mean "single and lonely" when placed together. His given name "Qiubai" (求敗) literally means "to seek defeat". His full name is thus roughly translated as "The Loner Who Seeks Defeat". It represents Dugu's status as an invincible swordsman who is haunted by solitude as no one can defeat or equal him in swordplay.
Dugu never made any appearances at all in any of the three novels. He is merely mentioned by name only as he lived in an age long before the events of the novels took place. He is briefly mentioned in The Deer and the Cauldron.
[Verse]
Y'all cats can't examine my stamina
I flow greater than eight of your favorite
Rap individuals
Trappin', I did it too...but not kilos of coke
More like these MC's in a chokehold
Gee whiz I'm loco, disregardin' my sanity
"Damn it he spits it so candidly"
Nit-wits can can it, please
Why my name don't get brought up
When South Carolina get thought up?
I oughta be whinin'
But I'm shinin' like I was the forehead
On Mario Winans
I'm sorry your highness...but this time it's official
I wish you wack rappers would strap a
B-bomb to your baby Timbs
Maybe then you'll blow up before I do
Your IQ is minus 2
