AO

..is short for ‘Adults Only’ (most extreme videogame rating in the U.S.). See also the other vg ratings: EC(Early Childhood), K-A(Kids to Adults; was replaced by 'E' in 1996), E(Everyone), E10+(Everyone ten years of age or older), T(Teen), M(Mature Audience), AO(Adults Only), and ESRB.

GTA:SA(Grand Theft Auto: San Andreas) is no longer rated 'M', but instead 'AO', and subsequesntly is no longer on the shelves, barely in stock at all.

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

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.

Armpit odour.
Also known as PO. Similar to BO but somebody with AO reeks very strongly of funky pits.
