The period of time following a break up from a relationship in which steady pussy was readily available. This refers to the need to begin jacking off again because the pussy one once cherished in their relationship is no longer available for every-day-use.

This is something one must prepare and train for prior to entering the said jack off season, much like spring training in baseball.
"Dude, I am about to break up with that cunt; I gotta start hitting the gym and working the forearms to start training for jack off season."

"That sucks!"
