i worked in a chartered accounting firm and i assisted in the audits/reviews and compilation engagements of dozens of companies of varying types .... nobody i encountered ever used "budget" in the context you do
you are misusing the term and as i said before, making a jackass out of yourself 
Well, in all due respect to you, I'm sure you are right. They would never from an accounting/auditing perspective, you are right. KPMG is in the room doing our audit right now. from a sales perspective though it is used, frequently, in all seriousness, it is.
I do apreciate what you are saying though, from that perspective, you are right.
