look up any word, like the eiffel tower:
 
1.
Slang for kebab when you're going to go and eat it (ie. lunch etc.). The whole act of going there and eating the kebab is thus called "The song of Keebelund" after the more famous operas.

If you spot an unfinished plate of kebab at any kebab joint, it is considered an "Unfinished song of Keebelund".
Frank: "Hey Jim, you wanna go listen to the song of keebelund?"
Jim: "Sure, I'm famished."
