Flacid Jack

When the porn or any other source of sexual pleasure isn't hot enough to give you a boner and your penis is flacid like a flap jack, but you still rub one off anyways.

"I was watching tub girl last night, but she didn't do it for me so I pulled a flacid jack just for the heck of it."

Heart Jack

The ability to induce pleasurable orgasmic sensations of the heart.

Heart masturbation.

Probably heart healthy and regulates good behaviour in humans.

An ability of romantics as well as spirituals.

Singing "Fall on your knees! O hear the angels' voices!" is a heart jack for the spiritually inclined.

When Person A's comment on Person B's status message/post has more likes and the thread that follows is all about that comment and not about the original post at all.
