quiet jack off 

Masturbating without making any noise so others do not hear you.

"Man, I've mastered the art of the quiet jack off. I'm able to masturbate while my roommate is sitting quietly studying in his room without him knowing a thing!"

cracker jack

A tasty treat consisting of popcorn, peanuts and a caramel candy coating. It's sold in old-school boxes (which come in a three pack) and although the primary consumers are young children, it's invariably located on the top shelf of the supermarket isle. Every box comes with a prize -- usually a little puzzle, temporary tattoo, or a valid Georgia driver's license.

Take me out to the ball game,
Take me out with the crowd.
Buy me some peanuts and Cracker Jack...

jack and jill 

Jack and Jill party: a gathering of males and females, who masturbate in front of each other for mutual stimulation and enjoyment. (Generally looking is encouraged but touching is not.)

From jack and jill, with reference to the nursery rhyme Jack and Jill.

Last weekend my wife and I went to a Jack and Jill party.

Stone-wall Jackson

When a male is expecting a date to end in sex, and is usually unpleasantly disappointed. Generally the date leaves the male feeling discouraged, and so sad they can't even muster up the enthusiasm to masturbate.

"Damn, I drove 15 miles in a blizzard to get some, and it ended in stone-wall Jackson. I couldn't even muster up the enthusiasm to masturbate!"
"What a bitch."
