Glass Basement 

The equivalent of the glass ceiling, but on the other end of the spectrum. The phenomenon wherein women are absent from the lowest, most difficult or most dangerous jobs. Despite claiming the desire for equality women do not fight to break through the glass basement.

The refusal to crack the glass basement demonstrated the hypocrisy of fighting to break the glass ceiling.

Glass Basement 

The phrase is used to describe the glass basement in IQ for men. At the opposite side of the IQ scale from The Glass Ceiling lays a «Glass Basement» which is the idea that while Males have the highest/ more distrubuted IQ levels, they also have the lowest.

The glass ceiling is discussed so often that people forget about the glass basement for Males.

The Glass Basement 

A phenomenon similar to The Glass Ceiling in which a woman is given more freedom to act sleazy or raunchy than a man of a similar stature.
