Chaos was a mythological place associated with disorder. When referred to as Hell, it hinted at an unpleasant afterlife—a deck officer once told Han Solo he would probably freeze to death in the icy plains of Hoth, to which Solo replied "Then I'll see you in Hell." The term could also be used as an expletive, such as when Clone trooper CT-782 "Hevy" asked what "the hell" a Rishi eel was after it took CT-4040 "Cutup."
According to a legend of the Naboo people, Chaos was a pit held back by six impenetrable gates. In a direct reference to that legend, the virtually fathomless core of Theed's power generator was kept behind six laser gates.
