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."
