Six Demon Bag 

The term Six Demon Bag comes from a line in the movie Big Trouble in Little China, and refers to a sack that contained the magical tools/potions of Egg Shen as he led Jack Burton, Wang Chi, and the Chang Sing in their desperate attack against the evil Lo Pan.

Egg Shen: Can see things no one else can see. Do things no one else can do.

Jack Burton: Real things?

Egg Shen: As real as Lo Pan!

Jack Burton: Hey, what more can a guy ask for?

Egg Shen: Oh, a six-demon bag!

Jack Burton: Terrific, a six-demon bag. Sen-sational. What's in it, Egg?

Egg Shen: Wind, fire, all that kind of thing!
