Ohio

Ohio is a popular meme in this current generation that's about well, Ohio, the American state. (if you dont know geography i literally will start thinking about how you didn't know this)
The videos that use the Ohio meme depict Ohio as a chaotic state with many monsters and weird human behavior.

Person 1: Heyyy, are you trying to enter Ohio?
Person 2: *nods*
Person 1: Follow me then.
