Nathan Fillion created the acronym ATS as the short form for: Across The Sky. It can be used in conjunction with other acronyms and phrases, such as ATW, which is short for: All The Way.

It means that which is:

•soaring through the sky

•all over the world

•throughout the universe

•forever and ever

to infinity and beyond
Here are some paraphrased usage examples for ATS (Across The Sky), along with some from the Twitter page belonging to NathanFillion:

When retweeting someone's tweet, Nathan Fillion said it went: "All the way across the sky (ATW ATS)."

The TV shows Castle and Firefly are so vivid, they are DRATWATS! (Double Rainbow, All The Way Across The Sky!). (DR ATW ATS)

The brilliance of Nathan Fillion is so intense, it's Full On Double Rainbow, All The Way Across The Sky! (FO DR ATW ATS!) (These can be combined into one acronym: FODRATWATS!)

ATS - Amway Tool Scam, the symbiotic relationship between Amway and the LCKs. When the LCKs asked for more of the Amway profit, Amway turned them down, but then ignored the FACT the upline was TOTALLY misrepresenting the business model by showing the Amway marketing plan, but in reality making most of the profit from their "tools" sold to the downline, yet leaving the ATS out of the presentation.
I thought my Amway upline made most of their profit from Amway, because that's how they show the Amway marketing plan, but then I found out most of their profit comes from the ATS, and most IBOs (distributors) in their group operate at a loss.
