When a male uses a jelly or preserves as a substitute lubricant to wank off and masturbate. Used either out of desperation for some form of lube or because of a food fetish.
Girlfriend: Hey!! Why does your cock taste like my grandma's homemade jelly again?
Boyfriend: Just suck it. I did a little Jelly Jacking earlier.
