1)Obviously, a reference to the Wu-Tang Clan, a hip hop group from Staten Island, comprised of the Rza, Gza, Ghostface Killah, Raekwon, Masta Killer, ODB (RIP), Method Man, Inspectah Deck, and U-God.
2)Also, where I'm from, a blunt laced with coke (NOT crack). Gives a speedy high.
wu, aka wu banger, is a blunt wit crack rocks in it, a dieablo is a blunt wit coke in it, "But it was just a dream for the teen, who was a fiend, Started smokin wu's at sixteen
And running up in gates, and doing hits for high stakes
Making my way on fire escapes
No question I would speed, for cracks and weed
The combination made my eyes bleed" raekwon from the wu tang clan "cream"
bill wu is really smart. not to be stereotypical of asians, since im sure bill is just naturally inclined to be a genius, and it has nothing to do with his asian heritage.
