glass plating 

A sexual act in which one person lies underneath a glass coffee table while a partner takes a dump on the table.

Don't go in that place on Kearny Street with the "nastiest videos in town" sign. They got glass plating in there.

Glass Plating 

It's when you put a glass plate over your face and a girl sh*ts on it!

Boy: Let's go glass plate behind the tree.

Girl: Nah, maybe later.

If there is grass on the playing field 

If the girl is old enough to have 'grass on the field' than she has reached puberty and has pubic hairs, making her 'game'.

"is your girl old enought?"
"Hey... if there is grass on the playing field, then play ball"
