When you intentionally leave without saying goodbye.
You're at a party, and you want
to go home early. You know that if you go say goodbye to your friends, they will
try to convince you to stay longer. So instead you slip
anyone seeing you leave. When your friends realize this, they will
say that you did a "Puerto Rican" or "Puerto Rican Fade"
This is a phrase used
in South Africa. I'm not sure if its used
anywhere else in the world. I cant seem to find the origins.
