After completing the horrifing test of -gulp- reading Twilight, you may discover many people asking you "Team Edward or Team Jacob?" This all started around New Moon and gradually grew even more rabid in Eclipse as fangirls started arguing over who Bella should have been with. The Teams were just about which character people liked more, and they became so well-known outside of the fandom that they received media attention everywhere. Of course, while some fans may claim that you have no choice but to be in one of the two teams, it doesn't stop antis and others from making their own.
