The emo kid went for a high five. People say he's still hanging.
The Emo Kid
Explanation
Explain Bear
Alright, listen up, dummy. This joke is dark. "Hanging" has two meanings: like hanging out with friends, but also, like, hanging yourself. Emo kids are often sad, so the joke implies the emo kid is dead. You probably didn't get it because you only hang out with yourself, dork.
