H is O
When you hear this, you better run, someone is coming for you like they're the last person on Earth who still knows how to spell 'glenn frey.'
Your friend just said 'H is O' and now you're terrified they're going to bring the heat at lunch.
You hear 'H is O' from the other side of the classroom and you know it's going to be a long day.
Your crush just said 'H is O' and now you're getting ready for the worst.
