Short for "stuck-in-between". An acronym for a group of mature and attractive women who are younger than than the usual age limit for a MILF, yet old enough for proper recognition.
Typical age range for a SIB is between 25 and 29, but there have been reported SIB sightings in women as old as 32.

My friends and I decided to hit up this cougar bar looking for some older women, but instead the bar was filled with SIB's.
Dude, did you just see how hot that SIB was, she was perfect!
SIB Conversation (Actual):
Young Man: Hey girls, how old are you?
Attractive Busty Woman and friend: Ummm...26?
YM: Wow that's perfect, you guys are just what we were looking for, SIBs!

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
Guy 2: Were they SIBS?
