(verb): The process in which one's scrotum becomes compressed and settles quite near the man's penis (hence the name 'cockballing') due to exposure of one's testes to cold weather, water--preferibly salt water--, and even ice.
"I knew that I would soon be cockballing if spent too much time swimming with the cute sailors." uhhhhhh

"Daily cockballing has become quite the hobby among most male snowboarders and skiiers."
