Jetsonic 

in the now old-fashioned style of the future as envisioned in the 1950's and 1960's, when it was assumed that all problems would be conquered by science by now, that we would live to 125, travel in personal spaceships, have robotic servants, and that Mom would prepare dinner in pill form with the touch of a finger in her space kitchen.

The old Star Trek episodes have a distinctly Jetsonic feel to them today.

That big concrete icon at LAX looks Jetsonic now.

Jewtonian 

A word(derived from Sir Isaac Newton, father of classical physics) used to describe most of 20th century physics, at least the relativistic and quantum mechanical part. The foundations are largely the result of the work and imagination
of a series of brilliant scientists of Jewish decent.

The Manhattan project was the triumph and tragedy of Jewtonian physics.

Justonian 

Just an absolute stud, everybody wants him. Hes a fucking champ, and everyone loves him. And he's so badass and sad and lonely that he has to make things up about himself on Urban Dictionary.

Justonian pretending to be someone else hoping for some reassurance: "Justonian is pretty awesome, huh?"
Someone else: "I've never heard of him, but he sounds like a faggot."

Jerkonian 

Today's version of Draconian. Creating processes, particularly at work, that are excessively harsh or severe. You know, something a jerk would do.

Our new head of marketing relaxed many of the Jerkonian rules his predecessor had in place relating to how much time we spend on parts of the business.

Jesonia 

Jesonia, a unique name made for a unique person born out of love. Jesonia is the kindest and most loving of people you can ever encounter in your life. Jesonia is full of energy, joy and kindness. The best friend, sister and daughter anyone can ask for. A hard-working person, she will always say yes and try her best to help you with anything you ask. She does not judge and is always ready to start a party. Her imitation of accents may not be the best, but she is unintentionally funny with her dry humour and puns that always puts a smile on your face.

Ask Sonia! Call Jes! JJ did it!

Jesonia is a noun, you could use it as an adjective depending on the situation.
