Members of the Sigma Iota Beta local sorority at Hope College. Every girl on campus wants to be a SIB but would deny it if asked. They like to party and have a good time but are also the girls you could take home to mom and dad. They are the most down to earth and involved on campus. If you meet a cool girl at Hope, odds are...she's a SIB.
Guy 1: I met these sweet girlslast night. They were hot, fun, and smart.
Guy 2: Were they SIBS?
Guy 1: Yeah
Guy 2: knew it
