I believe the answer is:

'tattered cloth' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rag that I've seen before include "Take the mickey out of" , "Fun week for college students" , "Bit of cloth" , "Waste piece of cloth" , "A tattered cloth or university frolic" .)
