Whats a slunk?

[manbehindthemask]

slunk is The skin of an unborn or prematurely born animal. The term is applied particularly to calves. So it is skin.

Ah that makes sense when you hear "save me the slunk".

But what about songs such as Johnny Be Slunk? I looked up slunk in the dictionary and it means "To pushed forward; to be moved, in a mental manner."
