I think I&#x27;ve only heard that term while shopping for a car (the salesmen kept saying he&#x27;d have to clear the deal through the &quot;back office&quot;)...he was lying...but anyway...<p>No, in terms of websites&#x2F;apps, I&#x27;ve never heard that term used. If I encountered that term on a site I would assume that the copywriter wasn&#x27;t from the US.
