When you see a friend or
acquaintance walking or driving by, instead of saying, "Yo
what's good?" You yell or say "YURRR!" You
usually get an "AYO" back from them.
Heather was walking down
Main Street when Julie, Rodney & Kathy happen to ride by on their way
out of town. Kathy sticks her out of the window and yells "YURRR!" to Heather. Heather replies with "AYO!" Than this usually leads to
one of them texting one another.
