The Duke vs. UK rivalry goes back nearly 2 decades.
Fan Outfitters cashed in on this fued and is known for their "Duke-hating" gear.
Their most recent shirt included the slogan: "I don't often hate, but when I do, I prefer to hate Duke".
Some said the shirts are distasteful, but many fans agreed that it is all in good sport.
Christopher Benavidez said he wears his "Duke-hating" shirt for superstitious reasons, "It has the most winning percentage".
Fan Outfitters also offers a wide variety of more tasteful, and colorful, gear.
