Question:

What does it mean when someone says "Black my eyes"?

---

I heard it on a few songs and im just curious =)

Answers: Take them out so i can't see anything that's why it says black (dark) my eyes. So i can't see anything. Punch them in the face?? maybe it means to commit suicide... Let's see...punch them in the eye; put on lots of makeup; close your eyes so you can't see bad things...could mean anything.
