The act of jerking off (typically a man), especially to the point of orgasm.

Originates from the term "jacking off" as well as the similarity of the "cracking" sound from performing it and the opening of usually alcoholic beverage bottles.
It is also a popular perversion of "cracker jack", the brand of caramel corn.
