Yes .
In NC , UNC Tarheels are referred to as Carolina [Carolina Blue]
NC State Wolfpack as State
Duke ... is Duke [tarheel fans pronounce it Dookie - yeh that kind of dookie]
UNC fans are so engulfed with their devotion, anything that shade of blue is immediately an infringement on their trademark, and falls under their patent.
They claim that God is a Tarheel fan, and the sky is Carolina Blue.
So its always a special thrill to whoop UNC, when you pull for State or Duke.
98% of Tarheel fans never attended ANY college, most never finished High School.
