RFP is not an idiom. It's an abbreviation.
There are a number of RFP's that have been released and some have even been returned.
Writing A Good RFP ResponseAn RFP response usually comes in the form of a Scope of Work document, or a proposal based on the requirements of the RFP. A good RFP will outline how your response should be written, and let you know all the information you need to provide, and how to provide it. If the RFP is not well written, I suggest you request a call with the potential client, and be prepared to ask specific questions that are not addressed in the RFP.
