How to spot a jit...
girls- seen wearing too much makeup, clothes that do not fit correctly, and a fake designer purse
boys- often a foot or so shorter than the girl, seen wearing the most "ganster" clothes possible even though they are often rich young white kids

Acronym for song "Jump" aka Jump in the stands written by and performed by former Green Bay Packer, Robert Brooks. JITS is a great song to play to get your friends fired up before Badger Football games and trips to the bar.

With enough alcohol (Preferably beer out of a basket or Gin shooters) JITS can be turned into an adjective to describe anything.
Hey Tyler, how about you fire some JITS on before the Badgers game

Hey Alex, how about we fire some JITS on so Tyler will get his ass off the front porch and back in here drinking

As an adjective:

Hey Bourque, sorry about you bed sheets, but Katch JITSed all over them.

I can't believe John JITSed out of here and to the Laundromat ......... must have been too much hot sauce.

A Florida prison term to refer to young thuggish men with no respect, restraint or life experience. Often starting fights for no reason, robbing anyone they can, going to solitary confinement a lot, and just generally not giving a shit. it is actually short for jitterbug, which describes the way that jail or prison makes them, like a tightly wound bundle of nerves as they have no maturity or self control. This tension is usually vented in methods that get them more prison time. Often young gangs will write "jit shit" along with their names in jailhouse graffiti. This is like a pride thing, embracing what was an insult. It's always the jjts to cause problems or drama. They thrive on mindless bloodshed and violence. Actually they are the most feared inmate, as they are willing to do anything for no reason, are reckless and unpredictable
Damn the guards got us locked down again over some stupid jit shit
