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!

Typically used to describe something that whips alotta ass.

A buzz word being used to refer to creators and influencers forming or encouraging unhealthy relationships with their fans. Usually used in the context of young audiences feeling they have a relationship with the influencer due to the huge amount of the influencer’s content they consume. The influencer in question, however, is unaware of the fan’s existence other than the general knowledge of having fans. Common examples include Dream and his stans. These relationships are exacerbated by the influencers confirming they have more than a creator-to-viewer relationship.

The word is circulating due to various YouTube essays about the phenomenon using the word, and therefore people who enjoy complaining about influencers repeating what they heard in the video in any comments section they can find.
