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 2: Were they SIBS?
Guy 1: Yeah
Guy 2: knew it

sib

SIB is an acronym for Strangers in a Bait Shop, which refers to having a stronger desire to impress people that you do not have any acquaintance with rather than to solve problems with someone who you are deeply connected with. The word derives from the episode of the Simpsons where Homer and Marge go on holiday to solve their marriage problems and Homer ends up spending the whole time trying to catch a giant catfish that 3 hillbillies in a local fishing bate shop were talking about. It is particularly significant to online and gamer relationships people have with each other that can take priority over real life issues.

Wife: Darling please, we need to speak about our marriage!

Husband: Listen, love. If I don't beat Bonk111 in the Fifa 09 International Cup final of Ultimate team, I won't get a wink of sleep tonight!! Let go of my arm, goddammit!!

Wife: How dare you sib me!
