In text and chat messages, AOAS stands for "all of a sudden." People use this acronym when discussing things that happened quickly and/or surprised them.
For example, if your friend recently got caught up in a whirlwind romance, they may text you "So AOAS, I have a new GF." This means your friend is surprised (and likely delighted) at how quickly their new romantic relationship has progressed.
