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.
