ballpumping

The masculine practice of enlarging the nads and ballsac, using negative air pressure to force more blood and lymphatic fluids to flow into the scrotum. Practitioners, called ballpumpers, wear a jar or specially designed cylinder over the genitalia and withdraw some of the air using a pump, thus "pumping" up their basket.

I had a great ballpumping session last night - got to 16" around! Barely fit into my jeans this morning!
