Ok ok so its not a word no biggie. If you listen to any hip hop at all you have probably heard this line upwards of 20 times. It comes from the Mobb Deep song "Shook Ones". this line is probably more popular than any other line in hip hop.
"Rock you in ya face stab your brain witch yer nosebone
You all alone in these streets cousin
Every man for dey self in dis lan' we be gunin'
an keep dem shook crew runin...."
-Mobb Deep "Shook Ones"
