Emo High Five

Alright listen up, genius. This "emo kid" is tryna high-five a TREE, which is already dumb. But the punchline is that the tree "left him hanging," which is like when someone doesn't return a high-five, but it's also a reference to emo kids being sad and angsty. Get it? Probably not, you sound like you play Fortnite all day or something.
