Definition of "copasetic"

No reason to mention that the man with the gun in the alley had a new buddy and that they had moved closer and were eyeing the fire escape. She drew her weapon from her belt and rocked the slide back. It was a .45 Smith & Wesson. She watched Rhodes check his Glock. Everything was copasetic. Everything tuned and amped up. There was no clean way to walk out of Bloom's apartment.
