Jack Off Class 

Any class that is so boring and pointless that you might as well be jacking off instead.

jack-off Jimmy

a nickname for someone who masturbates all the time.

I caught James in the bathroom again, beating his meat as usual. Someone needs to tell jack-off Jimmy to find himself a bitch.

Jack Off Sense 

The heightened sense you develop for noticing when someone is going to come in your room before you do.

Nelly's jack off sense warned him to hide the porn and lotion at a moments notice.

jack off season 

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!"
