AoS 

Arc of Suck

A term used to refer to bad storylines in TV shows.

It is most often used in Smallville forums to refer to the Season 8 arc when Lana Lang returned to Smallville for a few episodes, during which time Lois was absent.

After Lana came and went during the AoS, Clois really lost its mojo.

AOS is short for Academy of Science, aka "Academy of Swag". It's a Loudoun County Public School. The members attend their home high school, like Stone Bridge, Broad Run, Briar Woods... on one day and AOS on the other. It's the best of both worlds!

Woah, you go to AOS? You got swaaag.

AOS 

All Options Suck - None of the possible choices or outcomes are desirable.

We can spend Christmas at your parents or at my parents? That's an AOS scenario if I ever saw one.

Freqently the choices open to us in life are AOS. The only thing you can do is pick the least sucky one.
