There are a lot of things that you need to know when you first start couponing, and one is all of the abbreviations and terms/lingo that come along with the territory!  
When texting was first getting popular, I remember everyone freaking out about the abbreviations and "text slang" - heck, I still have to google what people mean sometimes when they send me "ROTFLMAO".  Uhhhh what?  
But no need to worry!  When you see a breakdown and the couponer is talking about their "MM" purchase, or their "ECBs" and "OOP", you will know right where to come to!  Your trusty coupon dictionary!  Here I have put together a list of the most common and frequent terms, abbreviations, and codes that you might find on coupon forums, facebook, or even here on my blog.  If there are some I missed, let me know!
