1.
A sexual act in which the customer lays under a glass coffeetable and looks up through it, while their partner defecates on the top. How some people find this stimulating I'll never know.

Also can refer to the same positioning with a coffee table but the person on top merely presses their genitals onto the glass, for "squashed" visual effect - or can refer to defecating onto someone's face which has been first covered in plastic kitchen wrap like Saran Wrap.

In this perfect addition to foreplay, one partner lies beneath a glass coffee table while the other squats above it and unloads. Like viewing the colorful sea life from the relative safety and serenity of a glass-bottom boat, this simple maneuver is not only arousing but biologically tantalizing.
I've been to Hawaii. I've seen all of those fish---its what every tourist does. It's neat and all, but never blew me away. But getting to see my Bobby in action, doing that Glass-bottom boat for me, seeing that magical human process going on in front of me . . .well, I just felt like a science student all over again.
