The meaning of the meme:

"I have good juice to eat with you" means "I have good fruit to eat with you". Nowadays, it is mostly used as an informal warning and intimidation among netizens.

The source of the meme:

"Good juice" is a homophonic meme of "good fruit". It first came from the series "Once Upon a Time in the Northeast" produced by the ancient Internet celebrities Tiger Brother and Dao Brother. In one of the lines, Brother Tiger said, "If you come to Shenyang, I won't have good fruit to eat without you." Because of the accent, "good fruit" sounds very much like "good juice." Therefore, netizens use "good juice" to refer to "good fruit" in a joke.

"I have good juice for you" originated from a video of the host/performance artist Yaoshui Ge teaching a liar. Because of his accent, fans made fun of him, and many famous lines emerged, "Little brother, I would rather not catch me, If I catch you, I’ll give you some juice”

Application examples:

Informal warnings between friends:

1: Brother, if your father finds out what you did, I will give you some juice.

2: My friend, don’t talk nonsense. If you say something wrong, you will be rewarded with juice.
