Is there an unwritten shorthand code for buyers to leave feedback?  I am not talking about all those flowery symbol things you can grab off the web, I mean anagrams or acronyms that mean certain things. 

I recently received feedback in one of my shops on a clothing item, positive rating, with just DR in the comments.  I have been wracking my brain trying to work out what it could mean.  Anyone?  I'm going to feel really silly if it is an obvious one, lol.
