reddit上一种可信的解释是,就是去死吧的意思

It’s a popular Korean meme referencing a line from a show called “검정고무신”
The meme alludes to a conversation that goes something like this in the show:
A: “you don’t even have a father”
B: surprised pikachu face “no, my dad is in the states / America right now! He’ll come back”
A: “no, you idiot! He’s not in the states, he’s in the heavens (he’s dead). You father died and you don’t even know that?”
B: crying pepe face
So a lot of people in Korea refer to the states to signify something is dead in joking contexts haha
