Simply meaning "yes" or "yay". This word is used at any occasion and at any time and place.
The word was mentioned on many Vines, and is being used by many Viners to imitate a "white girl". Some people use the word "yass" to create more of a "Starbucks, Chipotle, White girl".
"Hey, are you buying Chipotle?"

Y'ass. This is a clever colloquialism, derived from the merging og the word "you" and "ass." It is most commonly used when referring to someone, or something who is, was, or will be an "ass." This term was actually not 'created,' as such, one would be inclined to say that it 'developed.' You see, the term first came into use when a dashing young man repeatedly found that his good friend was constantly making a fool of himself. After a while, having to incessantly iterate that his friend was, indeed, an ass, our hero became tired, and began slurring his words, thus producing today's term "y'ass."
Goddamnit, Erika, y'ass, would you stop rubbing yourself with those socks? Listen, we've been over that ridiculous sock fetish of yours.
