It is a leaf that was common to found at any party as decoration. Its used in the city now has been substituted by paper decorations, lights, ribbons,etc. During the Christmas season you can still see it adorning the nativity scene.
You might have already guessed that if somebody says to you that you are like a pacaya leaf is because you are found at every party!
