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!

A man who regularly vacuum pumps his scrotum to enlarge the nads and the sac. Ballpumpers are usually also cockpumpers.
Look at the bulge in that guy's jeans! He must be a ballpumper.
That old guy is either a ballpumper or his ticker's not up to the task of clearing edema.
