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.
