Newjazz

Newjazz is a “nom de guerre” or sobriquet for a man or woman on a mission in a place they shouldn’t be attending; doing things that they shouldn’t be doing.

A cultural guide or insider gets you in and introduces you as “Newjazz” to protect your identity; and, to allow you to move more freely and safely while partaking of forbidden delights.

It is generally understood that a person baring the name “Newjazz” is a first time attendee AND his or her hesitancy and/or awkwardness should be forgiven until they relax and become more comfortable in the surroundings.

However, the price of this indulgence is some type of social initiation to formalize your relationship to the community in which you are a guest. This can take the form of a public performance based on “venue activity” or the intake of powerful substances that could potentially BLOW YOUR MIND.

This term is made popular by season 3 episode 8 of Atlanta named — not surprisingly — New Jazz.

1) Now all of you Cougars hide your claws! This “Cub” is my friend. Newjazz. Make him comfortable but DON’T BITE! Unless he wants you to.

2) This is my “celly” Newjazz. He from around my way. He hung out with 23rd street and them and he aight . He’s in on some cowboy shit; but he ain’t do it! Just some BULLSHIT! Y’all show him some love.
