To any unsuspecting person who does not attend NKEC it's just a sub with meatballs, tomato sauce and melted chesse.
But to anyone who does attend NKEC, it is the holy grail of food at the low budget cafeteria. It is a "crusty on the outside, tender and soft on the inside" sub stuffed full with scruptious meatballs, overflowing with delicious tomato sauce and it is all held together with the perfect amount of motza cheese.
On every third thursday of every month you can by this treat and get a small slushy and chips for a meazly $3.25!!!

A meatball sub is when a male places his pubicle sac and/or testicles into a woman's vagina. Preferably done during the menstrual cycle so that some sauce can accompany the meatballs.
