Simply the finest group of MCs ever to assemble as a group and one of the standout acts in hip-hop's golden era in the 90s.
Together they created what is possibly the greatest and realest hip-hop album of all-time in "Enter the Wu-Tang (36 Chambers)".
The Wu Tang Clan took hip-hop, musically, to the next level, with RZA creating timeless beats, GZA writing lyrics that put other rappers to shame and Raekwon pioneering a whole new sub-genre of hip-hop -
mafioso rap (a style that Jay-Z would later imitate).
With the exception of U-God (... Sorry), every single member of the Clan was/is exceptionally gifted, as demonstrated by their solo projects - Liquid Swords,
Only Built 4 Cuban Linx, Tical,
Supreme Clientele etc.
If you're reading this definition because you actually don't know who the Wu Tang Clan are - educate yourself.
Basically, don't fuck with the Wu.
Example:
Boy: Mommy, I fucked with
the Wu Tang Clan, am I in trouble?
Mother: Boy, you might as well
go kill yourself now and save the waiting.
