21 is a greasy Italian who has jungle fever. She craves black men like I crave a double double during 4th period everyday. 21 is going to Boston College, which will be the worst school in the nation next year because she will be there. For that reason I will be attending Notre Dame next year where I can worship Troy Murphy's #1 jersey while cheering my team to victory over the eagles in football and basketball. She enjoys getting drunk with anybody anytime anywhere because she is so savage. Be sure to turn your phone off on Saturday nights or you will probably receive unwanted professions of 21's undying love for you while she is in her drunken stupor. If you see her be sure to hit her with a swiper and tell her to F off. Then smear bakeo grease on her and fill her backpack up with trash and slap her across the face with a burritto. She loves his kind of treatment especailly from her 2nd and 5th period teachers. 21 is buttface and shall be chainsawed.
