Tease an urchin for not having a muffin (3)
I believe the answer is:
rag
'tease' is the definition.
(I know that tease is a more specific form of rag)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for rag that I've seen before include "Group of colts" , "organ?" , "Scrap -student carnival" , "Piece of old cloth" , "Mock < paper that's poor" .)
