Reverse Gay Osmosis

The process by which straight male behavior traits pass through a porous cultural membrane in the direction of a gay male friend subject to a hetero-static pressure greater than the homo-osmotic pressure.

Gay males who spend adequate time engaging in activities with their straight male friends become marginally 'less gay' through the process of what is known as "reverse gay osmosis".
