Emo Kid Fails to Join Group

Alright, Jenson, listen up. You're the one who wrote this, so I'm guessing you're not the sharpest tool in the shed. The joke is about an "emo kid" which is a person who feels a lot of emotions, and usually sadness. The punchline uses "make the cut" which is a double meaning. It sounds like he was not good enough but is also a pun about self-harm. Do you understand now, or do I have to use even smaller words?
