An absolutely fucking stupid way of writing the word "yes".
Length can vary between "yaas" and "yaaaaasssss", depending on how much of a prick the person saying it is.
Just spell it correctly, you cunt.
Person 1: "Do you want to go for a drink later?"
Prick: "Yaas!"
Person 1: "Scratch that, I'm going with someone who knows how to spell."

Absolute Cunt: "Yaaaaaasssss."
Person 2: "Oh for fuck's sake, just say "yes", 3 letters isn't hard!"

An expression of utter and consummate excitement.
It is more powerful than other generic expressions, such as "hooray" or "yay".

Abbreviation for Yet Another Account Syndrome; when some crappy little website requires you to make an account to do anything instead of implementing OpenAuth.
