: I've heard this expression used with reference to someone who is going on and on about something or possibly forcing an opinion on someone. Can anyone confirm this/provide the origin of the phrase?
That's what it means, and it comes from times past when soap was packed in sturdy wooden boxes for the retailer, who discarded the boxes, which were then appropriated as speaking platforms by people who intended to rant in public about some (e.g., political) issue.
